Abstract:
Herein, we developed a fully heterogeneous catalyst (Br-LDH), where the bromide and the hydroxyl are combined in layered double hydroxides (LDH) and cooperate very well in promoting the cycloaddition of CO₂ with epoxides. The selectivity and yield of propylene carbonate could reach 95.5% and 92.0%, respectively.
