【 摘 要 】

Various off-the-shelf Lewis acids in conjunction with various onium salts are screened for coupling reaction of CO2 with epoxides. Among the tested ones, VCl3/n-Bu4NOAc, VCl3/(n-Bu4NCl or PPNCl), FeCl3/n-Bu4NOAc, and AlCl3/n-Bu4NOAc are proved to be highly active. Propylene oxide, epichlorohydrin, styrene oxide, and cyclohexene oxide can be converted over 90% yields to the corresponding cyclic carbonates without the use of organic solvents under mild conditions by 0.1-1.0 mol% catalyst charge.
