摘要：
The cyclometallated compound [PtMe(SMe2)(C6H4CH=NCH2C6H4Cl-2)] (1) undergoes a displacement reaction with PPh3 to yield a cyclometallated platinum(II) compound [PtMe(PPh3)(C6H4CH=NCH2C6H4Cl-2)] (2), which has been characterized crystallographically. Complex 2 crystallizes in the monoclinic space group C2/c, with a = 38.402(4) angstrom, b = 7.993(3) angstrom, c = 18.563(3) angstrom, beta = 101.34(3)-degrees and Z = 8. The reaction of 1 with 1,2-bis(diphenylphosphino)ethane (dppe) yields [PtMe(dppe)-(C6H4CH=NCH2C6H4Cl-2)] (3) containing an unidentate C donor imine ligand and a chelating diphosphine. Oxidative addition of methyl iodide to 1 yields a cyclometallated platinum(IV) compound [PtMe2I(SMe2)(C6H4CH=NCH2C6H4Cl-2)] (4), which undergoes a displacement reaction of SMe2 by PPh3 to yield [PtMe2I(PPh3)(C6H4CH=NCH2C6H4Cl-2)] (5). Compound 5 can also be obtained by oxidative addition of methyl iodide to 2. The stereochemistry of compounds 4 and 5 is discussed.
