PRODUCTION OF ALCOHOL AND ACETALDEHYDE BY TOMATOES

Abstract

Source: JP60078927A [EN] PURPOSE:To produce an alcohol having triple bond, by reacting Mg with a carbonyl compound or oxirane compound and a halogenated propargyl compound at the same time in the presence of metallic zinc or zinc halide in an inert solvent, and hydrolyzing the reaction product. CONSTITUTION:(A) The compound of formula I (R1 and R2 are 1-14C alkyl, alkenyl, alkynyl, phenyl, benzyl, thienyl, etc.; one of R1 and R2 may be H) or the compound of formula II (R3 is H, 1-6C alkyl or phenyl) and (B) the compound of formula III (R4 is H or CH3; X is halogen) are made to react with Mg in an inert solvent (preferably THF) in the presence of metallic zinc or zinc halide (0.05-0.5mol per 1mol of the compound of formula I or formula II), and the reaction product is hydrolyzed to obtain the objective compound of formula IVor formula V. EFFECT:The objective compound can be produced in high yield without using particular apparatus. USE:Intermediate of agricultural chemicals, pharmaceuticals or perfumery. ;
