The poly γ N (β butylsulfide) ethylaminopropylsiloxane palladium complex was synthesized and characterized by XPS and IR. XPS data illustrated that coordination bonds were formed between palladium and nitrogen atom and sulphur atom of polymer in complex. The results of IR support the formation of coordination bonds as suggested by the XPS results. The title complex displayed the higher activity for the hydrogenation of nitrobenzene, allyl glycidyl ether, allyl phenyl ether and acrylonitrile in isopropanol at 40℃ under an atmospheric pressure of hydrogen.Terminal addition products were obtained from all olefins.The yields of adducts were varied from 75 to 90% except for styrene and cyclohexene. On the other hand, palladium complex showed good activity for the hydrogenation of 1 butene, butane was obtained.The selectivity and yield of the butane reach 77% and 65% respectively.
