Abstract

Studies were performed on the catalytic activity for olefin hydrosilylation shown by three rhodium complexes, [{Rh(μ-OSiMe)(cod)}] (I), [{Rh(μ-Cl)(cod)}] (II) and [RhCl(PPh)] (III), and three platinum complexes, [Pt(PPh)] (IV), [Pt(PPh)Cl] (V) and PtCl (VI), immobilized in a series of different anion-containing morpholinium ionic liquids. The effect of the kind of anion (its nucleophilic character) on the activity, stability and possibility of a catalytic system with multiple uses in the hydrosilylation process has been established. In the case of the best systems it was possible to reuse the same catalyst sample 10 times almost without any decrease in the activity and a TON value over 99 000 was obtained.

摘要

对三种铑配合物[{Rh(μ - OSiMe)(cod)}]（I）、[{Rh(μ - Cl)(cod)}]（II）和[RhCl(PPh)]（III）以及三种铂配合物[Pt(PPh)]（IV）、[Pt(PPh)Cl]（V）和PtCl（VI）固定在一系列不同含阴离子吗啉鎓离子液体中的烯烃硅氢化催化活性进行了研究。已确定阴离子种类（其亲核特性）对硅氢化过程中催化体系的活性、稳定性和多次使用可能性的影响。在最佳体系的情况下，同一催化剂样品可以重复使用10次，活性几乎没有任何下降，并且获得了超过99000的TON值。
