| 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. |

| Keywords: | Organosilicon polymeric crown ether Functionalized thia-aza crown ether Crown ether platinum complex Hydrosilylation catalyst |
