Über Diels-Alder-Reaktionen des C60-Fullerens Vorläufige Mitteilung

On Diels-Alder Reactions of the C₆₀-Fullerene We report on the regioselective [4+2] cycloaddition of Buckminsterfullerene C₆₀( 1 ) at room temperature with 2,3-dimethylbuta-1,3-diene and with the monoterpene 7-methyl-3-methylideneocta-1,6-diene (= myrcene) and on the spectroscopic characterization of the corresponding crystalling monoadducts 2 and 3 . According to these experiments, 1 acts as a reactive dienophile, which can be functionalized regioselectively under mild and controlled conditons.
