Abstract: Benzyl ester (I; R = substituted-alkyl, cyanoalkyl; A = phenoxy, phenylthio, benzyl) was prepd. by reaction of benzaldehyde II and RCOHal(Hal = Br, Cl) in the presence of phase transfer catalyst. Thus, II(A = phenoxy), 2-(4-chlorophenyl)-3-methyl butanoyl chloride, NaCN, a small amount of water and catalyst were reacted to give I(R = 2-(4-chlorophenyl)-3-methyl-butyl; A = phenoxy).
