Heterogeneous Peramnganate Oxidation of Styrene and Cinnamic Acid Deriatives:A Simple and Effective Method for the Preparatinof Benzaldehydes

摘要

Strene and cinnamic acid derivatives yield crrespondingly substituted benzaldehydes when oxidized by pernnaganate under heterogeneous conditions.Reaction of terminal aliphatic alkenes under similar conditions gives discouragingly low yields;however,ketones and ketols are obtained in vergy good yields from the oxidation of 2,2-disubstituted and trisubstitted alkenes,respectively.Alumnia and Amberlite IR-120 can be used as solid supports in these reaction swith equaly good results.
