概要 Synthesis of [60]fullerene (C60)-functionalized rotaxanes via Diels-Alder reactions with C60 is described. Diels-Alder reaction of C60 and sulfolene moiety as masked diene attached on the wheels of rotaxanes results in high yields of C60 incorporation. Rotaxanes are prepd. by tin-catalyzed urethane-forming end-capping reaction with isocyanate of pseudorotaxane having the wheel carrying C60 functionality as introduced by the Diels-Alder reaction. The Diels-Alder reaction was accomplished as end-capping reaction between C60 and pseudorotaxane bearing sultine moiety as masked diene on the axle terminal. A variety of C60-contg. [2]rotaxanes was prepd. in moderate to good yields by these Diels-Alder protocols.
