Metal-Free Catalytic Hydrogenation

Metal-Free Catalytic Hydrogenation

Phosphonium borates of the form R2PH(C6F4)BH(C6F5)2 are shown to be metal‐free 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.
