【摘要】 <正> 均相络合催化剂用不溶于反应介质的聚合物固载化,是催化剂发展方向之一。其中,以聚合物负载的过渡金属络合物研究最广泛,有的品种已工业化。本文作者曾合成了一些含三苯膦配位基的有机硅聚合物负载的络合催化剂,它们均具有良好的催化活性,但合成较困难。本文报道从较易得的co-氯代烷基三烷氧基硅烷出发合成的四种新的烟更多还原

【Abstract】 Four poly-ω-diphenylphosphinoalkylsiloxane, including poly-ω-diphenylundecyltrialkoxy-siloxane, palladium complexes have been synthesized. They all displayed high activity for the hydrogenation of olefins and nitrobenzene. The influence of the structure of monomers, the length of carbon chain from ligand to main chain, and the incorporation of non-complexable group on the activity and selectivity of the title catalysts have also been investigated.更多还原
