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.
