A General Synthesis of a-Substituted Acrylonitriles
Abstract During a study of synthetic approaches to naturally-occurring sesquiterpene lactones, a new synthesis of the α-methylene-y-butyrolactone group was developed1 and has subsequently been applied to the synthesis of various types of α-methylenecarbonyl compounds.2 The synthetic scheme suggested that α-substituted acrylonitriles would also be available by this method.
HALOMETHYL-METAL COMPOUNDS. I. PREPARATION OF PHENYL (TRIHALOMETHYL) MERCURY COMPOUNDS,
Abstract Detailed procedures for the preparation of C 6 H 5 HgCCl 3 , C 6 H 5 HgCCl 2 Br, C 6 H 5 HgCClBr 2 and C 6 H 5 HgCBr 3 by the Reutov-Lovtsova method are given. Evidence is presented which indicates that the reaction of phenylmercuric halide, haloform and potassium tert -butoxide forms C 6 H 5 HgCX 3 by way of nucleophilic displacement of halide ions from mercury by the trihalomethyl anion.
