• The reaction of alkyl (<I>E</I>)-3-phenylpropenoates with manganese(III) acetate in the presence of Cl<SUP>−</SUP> ions gave alkyl (<I>Z</I>)-2-chloro-3-phenylpropenoates and alkyl 2,3-dichloro-3-phenylpropanoates. Ethyl (<I>E</I>)-2,3-diphenylpropenoate yielded ethyl 2,3-dichloro-2,3-diphenylpropanoate. Alkyl 3,3-diphenylpropenoates gave mainly alkyl 2-chloro-3,3-diphenyl-propenoates. 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.
