摘要：
New neutral and cationic complexes [NiBr2(L1)] (1), [NiBr2(OPHPh2)(L1)] (2), [NiMe2(L1)] (3), [NiBr(PMe3)(L1)](Br) (4), [Ni(CH3CN)(PMe3)(L1)](BF4)(2) (5), [PdBr2(L2)] (6), [PdI2(L1)] (7), [PtMeCl(L1)] (8), [PtMe2(L1)] (9), [Pt(CH3CN)(2)(L1)](BF4)(2) (10), [Pt(L1)(2)](X)(2) [X = Cl (11a), Br (11b)], [PtX(L1)(2)](X) [X = Cl (12a), Br (12b)], where L1: [Ph2PCH2C(Ph) = N(2,6-Me2C6H3)(2)] and L2: [Ph2PCH2C(Ph) = N(2,6-(Pr2C6H3)-Pr-i)(2)], have been prepared and characterised. The molecular structures of 1, 2, 6, 7 and 9 have been determined. The complexes [PdBr2(L2)] (6), [PdBr2(L1)] and [PdMeCl(L1)] have been found to catalyse the Heck coupling of 4-bromoacetophenone with n-butyl acrylate under aerobic conditions.
