过渡金属铂、钯的叔膦卤素络合物多数具有催化性能。两价铂、钯络合物都是平面四方型结构,存在顺、反异构体。以核磁共振方法研究叔膦的铂、钯络合物结构文献中已有记述,但对环戊基叔膦除Grim等人测定了~(31)P NMR谱外,未见其它报道。至于环戊基叔膦铂、钯络合物的合成和结构研究尚属空白。本文测定了通式为MCl_2(PPh_n Cp_(3-n))_2的16个络合物的 The transition metal platinum, palladium, most of the tertiary phosphine halogen complexes with catalytic properties. Two platinum, palladium complexes are planar square structure, there cis, trans isomers. Studies on the structure of platinum and palladium complexes of tertiary phosphines by NMR have been described in the literatures, but there have been no reports on tertiary cyclopentylphosphine except for ~ (31) P NMR spectroscopy determined by Grim et al. As for the cyclopentyl tertiary phosphine platinum, palladium complex synthesis and structure of the study is still blank. In this paper, 16 complexes of the general formula MCl_2 (PPh_n Cp_ (3-n)) _2
