Completely Regioselective, Highly Stereoselective Syntheses of cis-Bisfullerene[60] Adducts of 6,13-Disubstituted Pentacenes

cis-Bisfullerene[60] adducts of 6,13-disubstituted pentacenes (R = Ph, 4‘-hydroxymethylphenyl) are synthesized in 75% to 85% isolated yields under kinetically controlled Diels−Alder conditions. The cycloadditions are completely regioselective and highly stereoselective, with only traces of the diastereomeric trans-bisfullerene[60] adducts forming.
