FAB-mass spectral and computational results suggest that [ZnBr(R2PO4)(2)](-) could be an active species for the coupling reaction. Decomposition of cyclic carbonates into epoxides and CO2 during the product recovery process via vacuum distillation was almost negligible even in the presence of a Zn-RTIL up to 130 degrees C.
