【Abstract】 Fluorous calix[4]resorcinarene can self-assemble stable hexameric capsules in fluorous solvent(FC-72)with eight water by hydrogen bond. Due to the differently chemical enviriment inside and outside of the capsules, the molecular capsules show the remarkable ability for catalyzing Diels-Alder reaction by encapsulation of the p-benzoquinone and cyclohexadiene at 50 oC in a FC-72/Hexane media. Among such system, fluorous soluble catalyst shows very high catalytic activity and the reaction yield in the presence of molecular capsules is dramatically increased (31 times) compared to absence of the molecular capsules. Furthermore, this reaction system offers an environmental advantage in that the fluorous catalyst solution can be recovered and recycled after the simple extraction of the fluorous insoluble products.更多还原
