The reaction of alkyl (E)-3-phenylpropenoates with manganese(III) acetate of Cl^- ions gave alkyl (Z)-2-chloro-3-phenylpropenoates and alkyl 2,3-dichloro-3-phenylpropenoates.Ethyl (E)-2,3-diphenylpropenoate yielded ethyl 2,3-dichloro-2,3-diphenylpropanoate.Alkyl 3,3-diphenylpropenoates gave mainly alkyl 2-chloro-3,3-diphenylpropenoates.Ethyl 1-cyclohexenecarboxylate gave ethyl 1,2-dichlorocyclohexanecarboxylate.Dimethyl malonate yielded dimethyl dichloromalonate and tetramethyl 1,2-dichloro-1,1,2,2-ethanetetracarboxylate.Substituted malonates resulted in α-chloro derivatives.Methyl phenylacetates gave α-acetoxy derivatives.
