摘要：
(Chemical Equation Presented) Phosphonium borates of the form R 2PH-(C6F4)BH(C6F5) 2 are shown to be metalfree hydrogenation catalysts (see scheme) that effect reduction of sterically hindered imines and aziridines, as well as B(C6F5)3-protected unhindered imines and nitriles, at relatively low H2 pressures and temperatures. © 2007 Wiley-VCH Verlag GmbH & Co.
