镍(Ⅱ)、钯(Ⅱ)、铂(Ⅱ)-环戊基苯基膦配合物的合成及表征

Synthesis and Characterization of Ni(Ⅱ), Pd(Ⅱ) and Pt(Ⅱ)-Complexes with Cyclopentyl (Phenyl) Phosphines

合成了十五种配合物MX_2[(C_5H_9)_nPPh_(3-n)]_2系列,其中M=Ni,x=Cl,Br,I;M=Pd,Pt,X=Cl;且C_5H_9代表环戊基,n=1,2,3.通过元素分析、远红外光谱及紫外光谱确定了这些配合物的化学组成和空间构型.讨论了不同配体对配合物结构的影响.

The conriguration of the cyclopentyl group is different from that of other alkyl group. In order to study the effect of the cyclopentyl group on the configuration of transition metal complexes, fifteen complexes of MX_2[(C_5H_9)_nPPh_(3-n)]_2 series have been synthesized, where (a) M=Ni, X=Cl, Br and I; (b) M=Pd and Pt, X=Cl, and C_5H_9=Cyclopentyl, n=1, 2, 3. Their chemical composition and configuration have been determined by elemental analysis, far IR and UV spectra, respectively.
