Abstract

In this manuscript, we provide a theoretical rationalization of the mechanisms that control double H-2 addition to an unsaturated 14 e cationic Ir(III) complex to yield a dihydride Ir(III) complex. Further, we also present two mechanisms that can explain the experimentally observed incorporation of deuterium into the tert-Butyl (Bu-t) groups of the N-heterocyclic (IBu)-Bu-t ligands.
