The unusual reactivity of chelating phosphane-imidazolium salts MesImEtPPh2++Br-, DIPP-ImEtPPh2 +Br-, and MesImEtPPh2+BF 4- towards the low-oxidation-state iridium complex [Ir(COD)(μ-Cl)]2 was studied. In the absence of a base, the C-H insertion at the C5 position of the imidazolium ring was the only reaction that occurred, with no normal NHC observed, leading to hydridoiridium(III) complexes. This reactivity was independent of the nature of the imidazolium counteranion and of the substitution pattern of the aryl group. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
