Abstract

Novel polysiloxane gels, to which platinum species are encapsulated, are prepared by treatment of polymethylhydrosiloxane with alkenes in the presence of Karstedt's catalyst. These gels act as reusable catalysts in the reduction of functionalized nitroarenes with H(2) to the corresponding substituted anilines without leaking the catalyst species.

摘要

通过在Karstedt催化剂存在下用烯烃处理聚甲基氢硅氧烷来制备包封有铂物种的新型聚硅氧烷凝胶。这些凝胶在将官能化硝基芳烃用H₂还原为相应的取代苯胺的反应中充当可重复使用的催化剂，且不会泄漏催化剂物种。
