Diels-Alder Adduct of C60 and 4-Carboxy-o-quinodimethane: Synthesis and Chemical Transformations
The Diels-Alder reaction of o-quinodimethanes to buckminsterfullerene C60 (1) affords thermally stable derivatives. 4-Carboxy-o-quinodimethane (4) was prepared in situ from 3,4-bis(bromomethyl)benzoic acid (3) and reacted with 1 to give the carboxy-substi

Co-catalyzed radical cycloaddition of [60]fullerene with active dibromides: Selective synthesis of carbocycle-fused fullerene monoadducts
An efficient and highly selective Co-catalyzed radical cycloaddition of [60]fullerene with active dibromides for the synthesis of three-, five-, six-, and seven-membered carbocycle-fused fullerene monoadducts has been reported. The controlled experiments unambiguously disclosed that the reaction proceeds through the formation of a fullerene monoradical as a key intermediate.
