【 摘 要 】

An efficient catalytic system consisting of H2O, Polyaluminium chloride (PAC) and Tetrabutylammonium bromide (TBAB) was applied to the cycloaddition of carbon dioxide (CO2) to epoxides under mild conditions. Their catalytic cycloaddition activities were found to be well correlated with H2O and polyaluminium chloride, which had a synergetic effect with the halide anion of TBAB. The presence of H2O and PAC could remarkably improve the yield of propylene carbonate (PC) by which the reaction yield is about 4-5 times higher than TBAB. alone.The catalytic system also exhibited excellent cycloaddition activities for various epoxide substrates.
