摘要

十一碳烯氧甲基一缩二乙二醇、二缩三乙二醇分别与１

２－β（β－羟乙氧基）苯双对甲苯磺酸酯在氢化钠存在下关环缩合

得到９－十一碳烯氧甲基－２

３－苯并１５－冠－５与９－十一碳烯氧甲基－２

３－苯并１８－冠－６．二者与三乙氧基硅烷反应产物以二氧化硅固载化

得到具有十一烯氧甲基连接基团的二氧化硅固载苯并冠醚．它们可与铂形成配合物．铂配合物对烯烃与三乙氧基硅烷的硅氢加成反应具有极好的催化效能

Abstract

Two new benzocrown ethers

9 -undecenyloxymethyl - 2

3-benzo- 15 crown- 5 and 18-crown - 6

were synthesized from 1

2 -bis (hydroxyethoxy) benzene bistosylate and corresponding undecenyloxymethylpolyethylene glycol via cyclcondensation in 22 and 20% yield

respectively. The crown ethers were subjected to hydrosilylation by triethoxysilane

followed by immbilization on fumed silica

and then reacting with potassium platinite in acetone under nitrogen atmosphere

sequentially. It was found that the platinum complexes exhibited very high catalytic activity for the hydrosilylation of olefins with triethoxysilane.The hydrosilylation of decene took place even the amount of silica-bound benzo-15-crown-5 platinum complex used was as low as 1×10-5mmol of Pt.In such a case

the decene used was 5.0mmol

the yield of decyltriehoxysilane was about 77% and the turnover number was as high as 380

000.
