2,2-Dichloroaldehydes and 2,2-dichlorocarboxylic acids from 2-picoline center dot HCl catalyzed chlorination of aldehydes

Abstract

An efficient preparation of 2,2-dichloroaldehydes and 2,2-dichlorocarboxylic acids has been achieved by chlorination of aldehydes using 2-picoline hydrochloride as recoverable catalyst.An efficient preparation of 2,2-dichloroaldehydes and 2,2- dichlorocarboxylic acids has been achieved by chlorination of aldehydes using 2-picoline hydrochloride as recoverable catalyst
