A novel type of Pt–C interaction and a model for the final stage in reductive elimination processes involving C–C coupling at Pt; synthesis and molecular geometry of [1,N,N′-η-2,6-bis{(dimethylamino)methyl}-toluene]iodoplatinum( II ) tetrafluoroborate

Square-planar complexes of the type R[graphic omitted]MX (M = Pt or Pd), containing the terdentate ligand 2,6-(Me2NCH2)2C6H3, undergo with MeI (M = Pt, X = BF4) oxidative addition and consecutive reductive elimination resulting in the formation of the complex BF4–[IPt[graphic omitted]R-Me]+ in which the C-aryl centre, at which C–C coupling has occurred, is bonded to the cationic Pt-centre by a novel Pt-to-C-interaction.
