Dual-ionic imidazolium salts to promote synthesis of cyclic carbonates at atmospheric pressure
文献摘要:
Novel dual-ionic imidazolium salts are shown to display excellent catalytic activity for cycloaddition of carbon dioxide and epoxides under room temperature and atmospheric pressure(0.1 MPa)without any solvent and co-catalyst leading to 96.1%product yield.It can be reused five times to keep the product yield over 90%.These intriguing results are attributed to a new reaction mechanism,which is supported by theoretical calculations along with the measurements of 13C NMR spectrum and Fourier transform infrared spectroscopy(FT-IR).The excellent catalytic activity can be traced to a CO2-philic group along with an electrophilic hydrogen atom.Our work shows that incorporation of CO2-philic group is an feasible pathway to develop the new efficient ionic liquids.
