Hydrosilylation of alkenes catalyzed by Rh ( PPh_3)_3Cl in ionic liquids: influence of medium on addition reaction 离子液体对Rh(PPh3)3Cl催化烯烃硅氢加成反应的影响
Ionic solid sulfonic acid was synthesized and used as heterogeneous catalyst to catalyze the addition reaction of indole and nitrobenzene to afford the products with moderate yields. By filtration and drying, the catalyst could be recovery and reused again. 该催化体系可以在异相条件下催化吲哚对硝基苯乙烯的加成反应,并可得到中等产率的加成产物。该固体催化剂只需过滤,烘干,即可实现催化剂回收和重复使用。
