Ionic Liquid-Immobilized Quinuclidine-Catalyzed Morita-Baylis-Hillman Reactions

摘要

The ionic liquid-bound quinuclidine catalyzed Baylis-Hill-man reactions were investigated.The IL-supported catalyst showed equally good catalytic activity as compared with its nonimmobilized counterpart.The corresponding Baylis - Hillman adducts were obtained in moderate to high yields in all the cases tested.The IL-supported quinuclidine can be readily recovered and reused six times without significant loss of catalytic activity.
