We report the first well-defined example of intermolecular aryl halide oxidative addition (OA) to Pt(II). Complexes of the type (IMes)PtMe<sub>2</sub>(L) and (IMes’)PtMe(L) (L = SMe<sub>2</sub>, pyridine; IMes = <i>N,N</i>-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene; IMes’ = cyclometalated IMes) undergo intermolecular OA of phenyl iodide (PhI) at 60 °C, producing toluene <i>via</i> reductive elimination from a proposed Pt(IV)-phenyl species. Isolation of a model Pt(IV) OA product provides evidence for a Pt(II)/(IV) pathway. The OA of PhI is not limited to Pt(II)-IMes complexes;analogous reactions also proceed with phosphine-ligated Pt(II) dialkyl complexes, demonstrating that this reaction is feasible for a variety of electron-rich Pt(II) complexes bearing labile ligands.
