     A process for preparing alkynols of Formula I comprises treating a compound of Formula II, ##STR6## wherein Q is a functionally-modified hydroxyl and Z, if m is 0, is alkyl of 1-6 carbon atoms in the alkyl substituted by Q or, if m is 1, is alkyl or alkyl substituted by Q, each of 2-6 carbon atoms in the alkyl, and X, n and m are as above, with a solvolyzing agent and the further optional step of hydrolytically cleaving a tetrahydropyran-2-yloxy group present in the product thus obtained. 
     DETAILED DESCRIPTION 
     In the specification, ##STR7## is referred to as &#34;Ar&#34; and ##STR8## as &#34;A&#34;. 
     Therefore, compounds of Formula I can alternatively be represented by either of Formula Ia a 
     
         Ar-[C(CH.sub.3)(OH)].sub.m --C.tbd.CR                      Ia 
    
     or Formula Ib ##STR9## wherein A, Ar, m, n and R have the values given above. 
     Compounds of Formula I therefore include those wherein: 
     (1) X is F; 
     (2) x is Cl; 
     (3) X is Br; 
     (4) n is 0, including each of (1)-(3); 
     (5) n is 1, including each of (1)-(3); 
     (6) m is 0, including each of (1)-(5); 
     (7) m is 1, including each of (1)-(5); 
     (8) R is hydroxyalkyl of 1-6 carbon atoms, including each of (1)-(6); 
     (9) R is straight-chain hydroxyalkyl of 2-6 carbon atoms, including each of (1)-(5) and (7); 
     (10) R is alkyl is 2-6 carbon atoms, including each of (1)-(5) and (7); and 
     (11) R is straight-chain tetrahydropyranyl-2-oxyalkyl of 2-6 carbon atoms in the alkyl, including each of (1)-(5) and (7). 
     In compounds of Formula I, n preferably is 0. Consequently, Ar preferably is a substituted 4-biphenylyl radical. X is preferably fluorine or chlorine, preferably in the p-position, but by X can also be present in the o- or m-position. 
     A preferably is o- or p-fluorophenyl, o- or p-chlorophenyl; secondarily m-fluoro or m-chlorophenyl or o-, m- or p-bromophenyl. 
     If n is 1, Ar preferably is 4-(4-fluorophenoxy)-phenyl or 4-(4-chlorophenoxy)-phenyl. 
     The parameter m preferably is 0. The hydroxyalkyl of R is then preferably hydroxymethyl, 1-hydroxyethyl, 1-hydroxypropyl, 2-hydroxy-2-propyl, 1-hydroxybutyl, 2-hydroxy-2-butyl, 1-hydroxy-2-methylpropyl, 1-hydroxypentyl, 2-hydroxy-3-methyl-2-butyl, 3-hydroxy-3-methyl-2-butyl, 4-hydroxy-3-methyl-2-butyl, 2-hydroxy-2-pentyl, 3-hydroxy-2-pentyl, 4-hydroxy-2-pentyl, 1-hydroxyhexyl, 2-hydroxy-3-methyl-2-pentyl, 3-hydroxy-3-methyl-2-pentyl, 4-hydroxy-3-methyl-2-pentyl or 5-hydroxy-3-methyl-2-pentyl. R can also be 2-hydroxyethyl, 3-hydroxypropyl, 4-hydroxybutyl, 5-hydroxypentyl or 6-hydroxyhexyl. 
     If m is 1 and R is alkyl, R is preferably unbranched. If m is 1 and R is hydroxyalkyl or tetrahydropyran-2-yloxyalkyl, the alkyl in the alkyl part of R have straight chains. Thus, R preferably is ethyl, n-propyl, n-butyl, n-pentyl, n-hexyl, 2-hydroxyethyl, 3-hydroxypropyl, 4-hydroxybutyl, 5-hydroxypentyl, 6-hydroxyhexyl, 2-(tetrahydropyran-2-yloxy)-ethyl, 3-(tetrahydropyran-2-yloxy)-propyl, 4-(tetrahydropyran-2-yloxy)-butyl, 5-tetrahydropyran-2-yloxy)-pentyl or 6-(tetrahydropyran-2-yloxy)-hexyl, as well as isopropyl, isobutyl or tert.-butyl. 
     Preferred compounds of Formula I are those in which at least one of R, X, m or n has one of the above-given preferred meanings. 
     Preferred compounds of Formula I are those wherein:

     Compounds of Formula I are prepared according to known methods, such as described, e.g., in Houben-Weyl, Methoden der Organischen Chemie, George-Thieme-Verlag, Stuttgart; and Organic Reactions, John Wiley &amp; Sons, Inc., New York, under the reaction conditions known and suitable for the desired reactions. Known variants, mentioned here in detail, can also be used. 
     Some of the starting materials for preparation of compounds of Formula I are known. Those which are new can be prepared according to known processes. The starting materials can also, if desired, be formed in situ and, without isolation from the reaction mixture, be immediately further reacted to give compounds of Formula I. 
     Compounds of Formula I are prepared by solvolysis, especially hydrolysis, of compounds of Formula II. In these, Q is a functionally-modified hydroxyl, e.g., a metal alcoholate or an acyloxy group. 
     Q is preferably a metal alcoholate OM in which M is an equivalent of a metal, e.g., an equivalent of an alkali metal or alkaline earth metal, especially of Li, Na, K, and Ca. Q can also be MgHal or CaHal, (Hal is Cl, Br or I). M can also be an equivalent of a heavy metal, e.g., of a metal of the first and second sub-Groups of the Periodic System, e.g., copper, silver, zinc, cadmium or mercury, as well as one of ZnHal or CdHal. 
     Compounds of Formula II (Q is OM) are preferably prepared in situ, e.g., under conditions for a Grignard reaction. They can be obtained by 
     (a) reaction of a ketone of the formula ArCOCH 3  with a metal acetylide of the formula MC.tbd.CR; 
     (b) by the reaction of a carbonyl compound of the formula R&#39;COR&#34;, wherein R&#39; is H or alkyl of 1-4 carbon atoms and R&#34; alkyl of 1-5 carbon atoms, provided that R&#39; and R&#34; together do not possess more than 5 carbon atoms, and wherein R&#39; and R&#34; each are H is m is 0, with a metal acetylide of the formula Ar[C(CH 3 ) (OH)] m  --C.tbd.CM; 
     (c) reaction of a ketone of the formula ArCO--C.tbd.CR with an organometallic compound of the formula CH 3  M; 
     (d) reaction of a ketone of the formula CH 3  CO--C.tbd.CR with an organometallic compound of the formula ArM, wherein Ar, R, M and m are as above; or 
     (e) reaction of a ketone of the formula Ar--C.tbd.C--COR&#39; or Ar--C.tbd.C--COR&#34; with an organometallic compound of the formula MR&#34; or MR&#39;. 
     These reactions expediently take place in an inert solvent at temperatures between about 0° and 100°, preferably at about 15°-50°, for reaction times of 10 minutes to 36 hours. 
     Inert solvents for this purpose include, e.g., ethers, such as diethyl, diisopropyl or diisobutyl ether, tetrahydrofuran (THF), dioxane, diethylene glycol diethyl or dibutyl ether; carbon tetrachloride; hydrocarbons, such as benzene, toluene or xylene possibly with oleic acid added; amides, such as formamide, acetamide, dimethyl formamide (DMF), diethyl formamide or dimethyl acetamide; acetals, such as methylal; dialkyl sulfoxides, such as dimethyl sulfoxide (DMSO) or diethyl sulfoxide; pyridine; and alcohols, such as methanol or ethanol. During the reaction, an inert gas, such as N 2  or argon, is possibly introduced into the system. 
     Instead of alkali metal acetylides, diamine complexes thereof, e.g., with ethylenediamine, preferably the lithium acetylideethylenediamine complex, can be used. 
     Advantageously, the metal acetylides can be formed in situ, e.g., using alkali metal and alkaline earth metal amides, hydrides or enolates, alkali or alkaline earth metals themselves or alkali organometallic compounds, such as phenyl or naphthyl sodium, potassium or lithium. 
     For reaction of carbonyl compounds with metal acetylides, alkaline catalysts, such as alkali metal or alkaline earth metal hydroxides, alcoholates or carbonates, e.g., NaOH, KOH, NaOCH 3 , KOCH 3 , Na 2  CO 3  or K 2  CO 3 , can be used. 
     KOH is preferably used in ether in the presence of a little ethanol. Preferably, a slight excess of the acetylene compound and of KOH for the given reaction conditions, is used. 
     Reaction of carbonyl compounds with metal acetylides can also be carried out in liquid ammonia, possibly with the addition of one of the above inert solvents. Preferably, a mole ratio of 1:1 is used, possibly under pressure, e.g., 1 to 50 atmospheres, at temperatures between about -77° and 30°. 
     Compounds of Formula II in which Q is OM and M is an equivalent of a heavy metal, such as Ag or Cu, are also obtainable in situ by reaction of a carbonyl compound with a corresponding metal acetylide in the presence of a catalyst. Copper or silver acetylides obtainable, e.g., by reaction of a corresponding acetylene or a Grignard compound with a heavy metal salt, e.g., copper (I) chloride, can be used as catalysts. 
     Compounds of Formula II are obtainable under the above-given reaction conditions by reaction of a metal acetylide of Formula Ar--[C(CH 3 )(OH)] m  --C.tbd.CM, wherein Ar, M, Hal, m and n are as above, with a corresponding alkylene oxide, e.g., ethylene oxide, propylene oxide, 1,2- or 2,3-butylene oxide, 2,2-dimethylethylene oxide or 1,2,2-trimethylethylene oxide. The reaction is preferably carried out in THF at temperatures between about -10° and 100°, preferably between -5° and 25°. The alkylene oxide is employed in gaseous or liquid phase, possibly with cooling and/or increased pressure, e.g., 1.5-10 ats. 
     Carbonyl compounds of formula ArCO--C.tbd.CR or CH 3  CO--C.tbd.CR are prepared, for example, by reaction of a carboxylic acid halogenide of the formula ArCOX or CH 3  COX, in which X is Cl or Br, with an acetylide of the formula Li--C.tbd.C--R, in, e.g., carbon tetrachloride. Carbonyl compounds of formula Ar--C.tbd.C--CO--R&#39; or Ar--C.tbd.C--CO--R&#34; are obtainable analogously by reaction of a carboxylic acid halide of formulae R&#39;--COX or R&#34;COX with an acetylide of the formula Ar--C.tbd.CLi. Carbonyl compounds of the formula Ar--COCH 3  are obtainable by the Friedel-Crafts acylation of compounds of formula Ar--H with, e.g., acetyl chloride. 
     Metal acetylides of formulae MC.tbd.C--R or Ar--[C(CH 3 )(OH)] m  --C.tbd.C--M can be obtained according to known methods by reaction of a corresponding acetylene with an alkali metal, such as Li, Na or K; an alkali metal hydride, such as LiH, NaH or KH or an alkali metal amide, such as LiNH 2 , NaNH 2  or KNH 2  in an anhydrous solvent, such as dioxane, DMSO, THF and/or liquid ammonia. Grignard compounds of the formula ArMgHal are obtainable from the corresponding halide and magnesium. 
     Q in compounds of Formula II can be present in the form of an acyloxy group, e.g., alkanoyloxy, wherein alkanoyl preferably is of up to 7 carbon atoms, e.g., acetyl or oenanthoyl; benzoyloxy; alkyl- or arylsulfonyloxy, wherein the alkyl preferably is of 1 to 6 and aryl preferably of 6 to 10 carbon atoms. The functionally-modified hydroxyl can also be alkoxy, wherein alkyl is preferably of up to 6 carbon atoms, aryloxy, wherein aryl preferably is of 6 to 10 carbon atoms, or aralkyloxy, wherein aralkyl preferably is of 7 to 11 carbon atoms. Q can also be Cl, Br or I, i.e., a hydrohalic acid ester group. 
     Compounds of Formula II wherein Q is alkanoyloxy, benzoyloxy, alkylsulfonyloxy or arylsulfonyloxy are obtainable by reaction of compounds of Formula II, wherein Q is Cl or Br with an alkali metal salt of the corresponding acid. By reaction of a halogen compound of Formula II (Q is Cl or Br) with an alkali metal alcoholate are obtained compounds of Formula II in which Q is an ether group. Reaction of compounds of Formula II (Q is Cl or Br) with potassium iodide in acetone gives compounds of Formula II in which Q is I. 
     Solvolysis of compounds of Formula II takes place in acidic, neutral or alkaline medium at temperatures between about -20° and 300°. As acidic catalysts are expediently used HCl, H 2  SO 4  or acetic acid, as well as acid-reacting salts, such as ammonium chloride. Basic catalysts are, for example, sodium, potassium or calcium hydroxide and sodium or potassium carbonate. The solvent is preferably water; an alcohol, such as methanol or ethanol; an ether, such as THF or dioxane, an amide, such as DMF; a nitrile, such as acetonitrile; and/or a sulfone, such as tetramethylene sulfone. Solvent mixtures, especially mixtures which contain water, can be used. 
     If m is 1, in compounds of Formula II, two Q can be present simultaneously and can be the same or different. If Z in Q is tetrahydropyran-2-yloxy, the solvolysis can be done so that only Q which is not in Z is split off. It is also possible simultaneously to cleave solvolytically, especially hydrolytically, both Q, e.g., under somewhat more severe reaction conditions, such as higher temperature and/or longer reaction times. If Z in compounds of Formula II does not contain a tetrahydropyranyl group, then the solvolysis must be done so that all Q are split off. 
     Metal alcoholates of Formula II (Q is OM) preferred as starting materials are expediently not isolated but rather hydrolyzed in situ with a dilute acid, e.g., sulfuric acid or hydrochloric acid, or with aqueous ammonium chloride solution, preferably at temperatures between 0° and 30°. 
     Compounds of Formula I, in which R is tetrahydropyran-2-yloxyalkyl, can, if desired, be cleaved hydrolytically, preferably by treatment with a dilute mineral acid, such as hydrochloric acid, in solvent mixtures, such as aqueous dioxane, at temperatures between 0° and 30°. 
     Compounds of Formula I contain a center of asymmetry and are usually present in the form of a racemic mixture. The racemates can be separated into their optical antipodes by mechanical or chemical methods described in the literature. 
     Compounds of Formula I possess valuable pharmacological properties, particularly, anti-inflammatory, lipid level-depressing and thrombocyte aggregation-inhibiting activity, as well as analgesic and antipyretic activity. Anti-inflammatory activity can be demonstrated in rats by the adjuvant arthritis test according to Newbould, Brit. J. Pharmacol., Volume 21, (1963), pages 127-136. Of lipid-depressing activity, cholesterol level-depressing activity is detectable according to Levine et al., Automation in Analytical Chemistry, Technicon Symposium 1967, Mediad, New York, pages 25-28, and triglyceride-depressing activity according to Noble and Campbell, Clin. Chem., Volume 16 (1970) pages 166-170. Thrombocyte aggregation-inhibiting, analgesic and antipyretic activity can be ascertained according to conventional methods. 
     Compounds of Formula I can be used as pharmaceuticals in human and veterinary medicine. 
     Compounds of Formula I can be used for the preparation of pharmaceutical preparations by formulation into a suitable dosage form together with at least one carrier or adjuvant material and possibly together with one or more further active materials. The thus-obtained compositions can be used as pharmaceuticals in human and veterinary medicine. 
     Carrier substances include organic or inorganic materials which are suitable for enteral, e.g., oral, parenteral or topical administration and which do not react with the new compounds, for example, water, vegetable oils, benzyl alcohols, polyethylene glycols, gelatine, carbohydrates, such as lactose or starch, magnesium stearate, talc, and vaseline. Forms for enteral administration are particularly tablets, dragees, capsules, syrups, juices, drops or suppositories; for parenteral administration, solutions, preferably oily or aqueous solutions, and suspensions, emulsions or implants; for topical use, salves, creams or powders. 
     The new compounds can also be lyophilized and the lyophilizates obtained used, e.g., for the preparation of injectable preparations. The stated compositions can be sterilized and/or contain adjuvants, such as lubricants, preservatives, stabilizers and/or wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, flavoring and/or aromatic materials. If desired, they can contain one or more additional active materials. 
     The substances of the invention are administered as for known antiphlogistics commercially available, e.g., Indometacine preferably in dosages between about 5 and 500 mg., especially between 10 and 250 mg. per dosage unit. The daily dosage preferably is between about 0.1 and 10 mg./kg. of body weight. 
     The dose for a particular patient depends, however, on the most varied factors, for example, effectivenss of the special compound employed, age, body weight, general state of health, sex, food, time and route of administration, rate of excretion, pharmaceutical combination and severity of the disease for which the therapy is applied. Oral administration is preferred. 
     Each of the compounds of Formula I in the following Examples is especially suitable for the preparation of pharmaceutical compositions. 
     Without further elaboration, it is believed that one skilled in the art can, using the preceding description, utilize the present invention to its fullest extent. The following preferred specific embodiments are, therefore, to be construed as merely illustrative and not limitative of the remainder of the disclosure in any way whatsoever. In the following Examples, the temperatures are set forth uncorrected in degrees Celsius; unless otherwise indicated, all parts and percentages are by weight. 
    
    
     In following Examples, &#34;usual work up&#34; means: If necessary, water is added to the reaction mixture, which is extracted with an organic solvent, such as benzene, chloroform or dichloromethane.
