A new simple and efficient transformation of carbonyl compounds to α-chlorocinnamates is described. Catalytic olefinationreaction with ethyl trichloroacetate gives target alkenes in moderate to good yields. The reaction with aromatic aldehydes proceeds stereoselectively to form preferably Z-isomers.
