Abstract

Zn-containing room temperature ionic liquids (Zn-RTILs), prepared from the reactions of ZnBr ₂ with 1-alkyl-3-methylimidazolium dialkyphosphates ([RMIm][R ₂PO ₄]), were highly active for the coupling reactions of CO ₂ with epoxides, producing corresponding cyclic carbonates in high yields. FAB-mass spectral and computational results suggest that [ZnBr(R ₂PO ₄) ₂] ^- could be an active species for the coupling reaction. Decomposition of cyclic carbonates into epoxides and CO ₂ during the product recovery process via vacuum distillation was almost negligible even in the presence of a Zn-RTIL up to 130°C.
