<unk>  is used for<unk> ation reactions, i.e., the introduction of an<unk>  group.<unk>  is an acyl group having the formula-C(=O)-CH3. For further information on the types of chemical reactions compounds such as<unk>  can undergo, see acyl halide. Two major classes of<unk> ations include esterification and the Friedel-Crafts reaction. Acetic acid esters and amide<unk>  is a reagent for the preparation of esters and amides of acetic acid, used in the derivatization of alcohols and amines. One class of<unk> ation reactions are esterification. :CH3COCl + HO-CH2-CH3 → CH3-COO-CH2-CH3 + HCl Frequently such acylations are carried out in the presence of a base such as pyridine, triethylamine, or DMAP, which act as catalysts to help promote the reaction and as bases neutralize the resulting HCl. Such reactions will often proceed via ketene. Friedel-Crafts<unk> ations A second major class of<unk> ation reactions are the Friedel-Crafts reactions.
