Abstract

The efficient synthesis of hydrosilanes by catalytic hydrogenolysis of chlorosilanes is described, using an iridium (III) pincer catalyst. A careful selection of a nitrogen base (incl. sterically hindered guanidines and phosphazenes) can unlock the preparation of Me$_3$SiH, Et$_3$SiH and Me$_2$SiHCl in high yield (up to 98%), directly from their corresponding chlorosilanes.
