Application of polyethyleneglycol (PEG) functionalized ionic liquids for the rhodium-catalyzed hydrosilylation reaction of alkenes

• [PEG400DIL][X] had been successfully synthesized and applied in the hydrosilylation.
• [PEG400DIL][X]-Rh(PPh3)3Cl catalytic system exhibit excellent catalytic performance.
• Effect of anion on hydrosilylation had been investigated.
• Catalytic system is stably and could be recycled.

Rh(PPh3)3Cl–polyethyleneglycol (PEG) functionalized ionic liquids with various anions were used as a catalytic system for the hydrosilylation reaction of alkenes. The influence of the anion of the ionic liquid has been investigated. It was found that the anion has an impact on the catalytic activity and selectivity. [PEG400DIL][PF6]-[Rh(PPh3)3Cl] shows an improved catalytic performance towards the hydrosilylation reaction of alkenes. The scope of alkenes and recycling of the catalytic system have been investigated.
