摘要：

The reaction of (eta5-C5H4)CMe2-eta5-(C13H8)ZrMe2 with (C6H5)3CB(C6F5)4 in toluene at ambient temperature leads to the formation of the [(eta5-C5H4)CMe2-eta5-(C13H8)ZrMe]+ cation in solution. The chemically highly-reactive cation can be stabilized and isolated by addition of a stoichiometric amount of the Lewis base PMe3 to the reaction mixture. The stabilized cation has been characterized by NMR spectroscopy and an X-ray diffraction study.
