Commercially available Iron(0) Fe2(CO)9 pre-catalyst can promote the selective desulfurization of secondary and primary carboxamides leading to the corresponding secondary amines and nitriles, respectively. The reaction is conducted under hydrosilylation conditions using phenylsilane or diethylsilane blue LED irradiation (2x24W, 450-460 nm) at ambient conditions.
