g-C3N4 and tetrabutylammonium bromide catalyzed efficient conversion of epoxide to cyclic carbonate under ambient conditions†
Abstract
A g-C3N4 and n-Bu4N+Br− combination is used for the first time for the conversion of epoxides to cyclic carbonates under CO2 filled balloon conditions. This combination was found to be very efficient for the conversion of a wide number of epoxides.
