摘要: 有机硅聚合物为载体的过渡金属三苯膦络合物,文献中只报道过聚γ-(p-二笨膦苯基)丙基和聚δ-(p-二苯膦苯基)丁基硅氧烷铑络合物,过去,我们曾合成了聚γ-(m-二苯膦苯基)丙基硅氧烷钯络合物,并证明了它是烯烃和硝基苯氢化的良好催化剂,本文报道上述高分子配位基与铂的络合物的结构与它在氢化反应中的催化特性。

Abstract: A new polymer-bound complex catalyst, fumed silica supported poly-γ-(m-diphenylphosphinophenyl)propylsiloxane platinum complex, has been synthesized starting from γ-(m-chlorophenyl)propyltrimethoxysilane via phosphination with lithium diphenyl phosphide and then immobilized on silica followed by treating with potassium chloroplatinite. Nitrobenzene, 1-hexene, styrene and acrylnitrile were used as substrates to evaluate the catalytic behavior of the title catalyst in catalytic hydrogenation reaction. The structure of the catalyst was characterized by IR, XPSand elemental analysis.
