Abstract:
A process for the production of cyclic carbonates comprising contacting an epoxide with carbon dioxide in the presence of a dimeric aluminum(salen) catalyst, and a co-catalyst capable of supplying Y−, where Y is selected from Cl, Br and I, where the dimeric aluminum(salen) catalyst is of formula I:
