摘要：

The bis(arylimino-Cp)ZrCl2 complex (I) forms an "antagonistic" Lewis pair with B(C6F5)(3), Treatment with dihydrogen yields the aminomethyl-Cp hydrogenation product (II) by means of a quasi-autocatalytic process. The salt III is an efficient catalyst for the hydrogenation of bulky imines and of silyl enolethers.
