Abstract
A novel, versatile one-step synthesis of o-dichlorobenzaldehydes has b een developed. Acyclic alpha,beta-epoxy ketones undergo the Vilsmeier reaction to afford o-dichlorobenzenemono- and dicarboxaldehydes wherea s cyclic alpha,beta-epoxy ketones gave o-dichlorobenzenecarboxaldehyde s and chlorobenzenedicarboxaldehydes.
