  摘要：

  The hydrolysis-polycondensation of palladium (Pd) and platinum (Pt) complexes of phosphines [p-(OiPr)(3)SiC6H4](2)PC6H5 and [p-(OiPr)(3)SiC6H4](3)P gives rise to xerogels in which the metal complexes are included within a silica matrix with retention of the arrangement around the metal centre. However, the trans-Pd as well as the trans-Pt complexes incorporated within the xerogels slowly isomerize into the more stable cis complexes. Direct reaction of (CH3CN)(2)PdCl2 with xerogels; prepared from both phosphines leads to the incorporation of the Pd salt, the corresponding complexes always adopting a cis arrangement of the ligands. Treatment with nBu(3)P of all the materials containing metal centres leads to the complete removal of the metal except for the materials obtained by hydrolysis of the metal-[p-(OiPr)(3)SiC6H4](3)P Complexes.

  摘要：

  对溴（三异丙氧基甲硅烷基）苯 2 与镁反应生成相应格氏试剂的稳定 THF 溶液。后者与 PCl3 或 PhPCl2 反应分别制备膦 4 和 5。 LiAlH4还原4得到膦6。化合物4和6已转化为磷衍生物，包括BH3、W(CO)5、铂和钯络合物，它们都带有三个可水解基团。这些磷衍生物在酸催化剂存在下水解和缩合，形成含有磷中心的新型有机-无机杂化硅胶。固态 13C、29Si、31P NMR 光谱用于评估有机部分的完整性并确定网络材料中的水解和缩合程度。结果表明，在溶胶-凝胶过程中，磷中心周围没有变化。干凝胶是无定形微孔材料，根据实验条件，比表面积介于小于 10m2g1 至 800m2g1 之间。与这些结果相反，在三-(三异丙氧基甲硅烷基甲基)膦7和三(三氢甲硅烷基甲基)膦8的水解和缩聚过程中观察到SiC键的完全断裂。

  The reaction of p-bromo(triisopropyloxysilyl)benzene 2 with magnesium led to stable THF solutions of the corresponding Grignard reagent. The reaction of this latter with PCl3 or PhPCl2 allowed the preparation of phosphines 4 and 5 respectively. LiAlH4 reduction of 4 afforded phosphine 6. Compounds 4 and 6 have been transformed into phosphorus derivatives including BH3, W(CO)5, platinum and palladium complexes, all of them bearing three hydrolysable groups. Hydrolysis and condensation of these phosphorus derivatives in the presence of an acid catalyst result in the formation of new hybrid organic-inorganic silica gels incorporating phosphorus centres. Solid state 13C, 29Si, 31P NMR spectroscopies were used to evaluate the integrity of the organic moiety and to determine the degrees of hydrolysis and condensation in the network materials. It was shown that during the sol-gel process there is no alteration around the phosphorus centre. The xerogels are amorphous microporous materials with specific surface areas lying between less than 10m2g1 and 800m2g1 depending on the experimental conditions. In contrast with these results, complete cleavage of the SiC bonds was observed during the hydrolysis and polycondensation of the tris-(triisopropyloxysilylmethyl)phosphine 7 and of tris(trihydrosilylmethyl)phosphine 8.
