α-Olefinated carbonyl derivatives have been obtained in good yield under very mild conditions by Wittig-type reaction of some conjugated azoalkenes with carbomethoxymethylene triphenylphosphorane. The reaction mechanism seems to implicate zwitterionic rather than cycloadduct intermediate, as usual for the Wittig reaction.
