【Abstract】 Cycloaddition between propylene oxide and carfor dioxide was invest igated in the presence of metaloxide supported potassiurn iodide. The results show that potassium iodide supported on amphoteric metal oxidesis highly active towards the cycloaddition. Propylene carbote can be efficiently swithesized with KI/ZnO ascatalyst under optimal conditions. Supports play an important promtion role in the cycloaddition.更多还原
