摘要
本文制备了一系列聚乙二醇-硅基双功能化咪唑型离子液体并进行了核磁表征,进一步应用于Rh(PPh_3)_3Cl催化烯烃硅氢加成的反应中.研究了不同链长离子液体、离子液体用量及其不同烯烃对催化效果的影响.在无溶剂条件下,该催化体系表现出较高的烯烃转化率及良好的产物选择性.
A series of polyethylene glycol-silyl double functionalized ionic liquids were synthesized, characterized by 1H NMR spectroscopy, and applied in the hydrosilylation of alkenes catalyzed by Rh（PPh3 ）3 C1. The effects of different lengths of ployether chain, different dosages of ionic liquid and different types of substrates on the hydrosilylation were investigated. Under solvent-free conditions, these catalyst systems showed high olefin conversion rate and good selectivity.
