    High Quantum Yield Molecular Bromine Photoelimination from Mononuclear Platinum(IV) Complexes
    摘要:
    Pt(IV) complexes trans-Pt(PEt3)(2)(R)(Br)(3) (R = Br, aryl and polycyclic aromatic fragments) photoeliminate molecular bromine with quantum yields as high as 82%. Photoelimination occurs both in the solid state and in solution. Calorimetry measurements and DFT calculations (PMe3 analogs) indicate endothermic and endergonic photoeliminations with free energies from 2 to 22 kcal/mol of Br-2. Solution trapping experiments with high concentrations of 2,3-dimethyl-2-butene suggest a radical-like excited state precursor to bromine elimination.

  • Reactions of methyl fluorosulphate and triethyloxonium tetrafluoroborate with transition-metal complexes

    Reactions of SFO2(OMe) and [Et3O][BF4] with a variety of transition-metal complexes have been examined and classified as ligand abstraction, oxidative additions, oxidation, ligand alkylation, or reactions in which an anion fragment is abstracted from a ligand. Factors influencing the mode of reaction and the mechanisms of some of the reactions are discussed.

    Abstract A mechanistic study is described for the electrophilic cleavage of the Pt C σ bond in complexes cis -[PtPh 2 (PEtPh 2 ) 2 ] and trans -[PtXR(PEt 3 ) 2 ] (X = Cl and Br, R = Me, Et, n-Pr, n-Bu, CH 2 Ph) by the proton in the presence of halide ions in aqueous methanol (MeOH/H 2 O, 91v/v) which yields cis -[PtClPh(PEtPh 2 ) 2 ] and trans -[PtX 2 (PEt 3 ) 2 ], respectively. The reactions are first-order

    The complexes [PtX(PEt3)2}2PH2]Y (X = H, Y = Cl or Br; X = Y = Cl or Br) have been prepared, and the structures of two isomers in CDCl3 solution have been determined by 31P n.m.r. spectroscopy. Both isomers are linked by single PH2 bridges. The halide complexes partly decompose to give [(Et3P)X2Pt(µ-PH2)PtX(PEt3)2] in CDCl3 solution. Analogous iodide complexes have been identified from their 31P n

    at 180 K to give [PtCl2H2(PEt3)2], (5), and the previously unknown [PtCl(PEt3)2(P′Cl2)], (4). On warming to 240 K, complex (5) decomposes and (4) is reversibly protonated to give [PtCl(PEt3)2(P′Cl2H)]+. Above 240 K, (4) is converted into the novel [PtCl(PEt3)2(P′Cl2H2)], (8). This complex is stable in solution up to 260 K, but decomposes irreversibly at higher temperatures. Changes in the n.m.r. spectra
