B(C6F5)3-Catalyzed Hydrosilation of Imines via Silyliminium Intermediates
Abstract

A broad range of benzaldimines and ketimines can be hydrosilated efficiently, employing B(C6F5)3 as a catalyst in conjunction with PhMe2SiH. Spectral evidence supports the intermediacy of a silyliminium cation with a hydridoborate counterion formed via abstraction of a hydride from PhMe2SiH by B(C6F5)3 in the presence of imines.
