Diarylplatinum(II) compounds as versatile metallating agents in the synthesis of cyclometallated platinum compounds with N-donor ligands

Abstract

This review deals with the reactions of diarylplatinum(II) complexes with N-donor ligands to produce a variety of cycloplatinated compounds including endo-five-, endo-seven-, endo-six- or exo-five-membered platinacycles. The observed reactions result from a series of oxidative addition/reductive elimination processes taking place at platinum(II)/platinum(IV) species and involving C-X (X = H, Cl, Br) bond activation, arene elimination, and, in some cases, Caryl-Caryl bond formation.
