Abstract

Imidazolium zinc tetrahalides, (1-R-3-methylimidazolium) ₂ZnX₂Y₂ (R=CH₃, C₂H ₅, n-C₄H₉, CH₂C₆H ₅; X=Cl, Br; Y=Cl, Br), prepared by reacting ZnX₂ with (1-R-3-methylimidazolium)Y, were found to have surprisingly high activities for the coupling reaction of CO₂ and ethylene oxide or propylene oxide to produce corresponding cyclic carbonate. The catalytic activity of imidazolium zinc tetrahalide was greatly influenced by the nature of halide groups bonded to the zinc center. The catalytic activity was found in the order of [ZnBr₄]^2->[ZnBr₂Cl₂] ^2-≫[ZnCl₄]^2-. The turnover frequencies (TOF: h^-1) increased with increasing temperature, but remained almost unchanged with the increase of pressure.
