Article abstract of DOI:10.1016/S0040-4039(00)82192-9

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.
