[PtMe2Me2NCH2CH2NCH(3,5-C6H3Cl2)–N,N′)}] (3e), arising from coordination of the ligand to the platinum center, is obtained at room temperature. The reactions of 1 with ligands PhCH2NCHAr (Ar=2,3,6-C6H2Cl3 (2g) and 2,3,5-C6H2Cl3 (2h)) produce cyclometallated [C,N] platinum(IV) complexes. The reactivities of the platinum complexes towards phosphines and methyl iodide have been studied. All complexes have been
