Abstract Commercially available iron(0) Fe2(CO)9 precatalyst 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 and blue LED irradiation (2 × 24 W, 450–460 nm) at ambient conditions.
