摘要

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.
