Abstract

Iridium^III complexes are attractive candidates for direct functionalization of abundant alkanes, such as methane. However, iridium catalysts have received little attention. This study focuses on iridium complexes containing η⁵-C₅Me₅ (Cp*) and monodentate N-heterocyclic carbene (NHC) ligands. The complexes [Cp*Ir^III(NHC)(Me)]⁺[MeB(C₆F₅)₃]^- activate the C-H bonds of hydrocarbons and activate molecular oxygen. The latter reaction forms the unusual oxo-bridged dimer [{Cp*Ir(NHC)(Me)}²(μ-O)]²⁺[2{MeB(C⁶F⁵)3}]^2-, which has been characterized by NMR and optical spectroscopies as well as single crystal X-ray diffraction analysis.
