过渡金属五卤苯基化合物的研究(Ⅶ)——双(二苯基烷基膦)合(σ-五溴苯基)溴化镍(Ⅱ)的合成和反应

Study on Transition-Metal Organic Compounds Containing Perhaloaryl Ligands(Ⅶ)——Synthesis and Reactions of Pentabromophenylnickel Complexes with Diphenylalkylphosphine

一般认为由于含卤基团较大的电负性,过渡金属有机化合物的稳定性随有机基团的氢为卤素取代而增加。在有机镍化学中,由于合成、结构和催化性能方面的兴趣,过去和最近对含有Ni—C_(6)F_(5)和Ni—C_(6)Cl_(5)键的化合物进行了广泛的合成及其反应的研究。

The complexes of general formula(ph_(2)PR)_(2)Ni(C_(6)Br_(5))Br(R=CH_(3),C_(2)H_(5),n-C_(3)H_(7),ph)were synthesized.Their chemical reactions with inorganic halides and pseudohalides were investigated and compared With corresponding C_(6)Cl_(5)containing complexes.
