Abstract

Innocent until proven guilty: The bis(2-picolyl)amine (bpa) and related poly(picolyl)amine ligands might not be as innocent as they seem. A double deprotonation of the amine (see scheme) and one of the methylene protons of [Ir(bpa)(cod)]+ is unexpectedly easy and yields the anionic complex [Ir(bpa−2H)(cod)]−, which is subsequently oxidized to the ligand-centered radical [Ir(bpa−2H)(cod)]. even in the air.
