摘要： 二(β-氯乙基)烯丙胺与3,6-二氧杂辛-1,8-二硫醇在乙醇钠存在下关环缩合,得到具有烯基侧链的1,7-二硫杂-10,13-二氧杂-4-氮杂-4-烯丙基环十五烷.后者通过硅氢加成、二氧化硅固载.再与氯亚铂酸钾反应,合成了一种新型有机硅聚合物负载硫、氮杂冠醚及其铂配合物.该配合物对于烯烃硅氢加成反应具有良好的催化性能.

Abstract: Di-(β-chloroethyl)allylarnine reacted with 3,6-dioxa-1,8-octamethylene dimercaptan in the presence of sodium ethoxide as condensating agent via.cyclizative condensation to give N-aliyl-l,7-dithia-4-aza-10,13-dioxa-cyclopentadecane.The latter was subjected to hydrosilylation with triethoxysilane,immobilization on furned silican,in sequence,and then reacted with potassium chloroplatinite.Anew type of organosilicon polymer-supported thia-aza crown ether and its platinum complex were obtained.It was found that this platinum complex was an efficient catalyst for the hydrosilylation of olefins with triethoxysilane.

Key words: Organosilicon polymeric crown ether, Functionalized thia-aza crown ether, Crown ether platinum complex, Hydrosilylation catalyst
