Quaternary onium tribromide catalyzed cyclic carbonate synthesis from carbon dioxide and epoxides

Novel and efficient organic catalysts of quaternary onium tribromide and the related metal-containing catalysts of SalenCoX/PTAT were developed to catalyze the coupling reaction of carbon dioxide and epoxides generating relevant cyclic carbonates including chiral propylene carbonate under extremely mild condition.
