A novel, versatile one-step synthesis of o-dichlorobenzaldehydes has been developed. Acyclic alpha,beta-epoxy ketones undergo the Vilsmeier reaction to afford o-dichlorobenzenemono- and dicarboxaldehydes whereas cyclic alpha,beta-epoxy ketones gave o-dichlorobenzenecarboxaldehydes and chlorobenzenedicarboxaldehydes.
