The first well-defined zirconocene complexes processing vinyl-imine and keteniminate species have been achieved from zirconacyclopentenesor zirconacyclopentadienes and two equiv of Ph2CHCN. Multifunctional effect of Ph2CHCN is observed for the first time in one system. This process proceeds via the azazirconacyclopentadiene intermediate and its intramolecular proton transfer.
