C-H activation in IrIII and N-demethylation in PtII complexes with mesoionic carbene ligands: examples of monometallic, homobimetallic and heterobimetallic complexes

Abstract

Mononuclear PtII and the first dinuclear PtII complexes along with a cyclometalated heterobimetallic IrIII/PdII complex bearing mesoionic carbene donor ligands are presented starting from the same bis-triazolium salt. The mononuclear PtII complex possesses a free triazole moiety which is generated from the corresponding triazolium salt through an N-demethylation reaction, whereas the mononuclear IrIII complex features an unreacted triazolium unit.
