资源简介：
The first well-defined zirconocene complexes processing vinyl-imine and keteniminate species have been achieved from zirconacyclopentenes or zirconacyclopentadienes and 2 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. Moreover, β,β′-C–C bond cleavage of tetra-alkyl-substituted zirconacyclopentadienes is observed for the first time under the appropriate conditions.
