Abstract
Thermal Diels-Alder reactions between C(60) and electron-deficient 3, 6-diaryl-1,2,4,5-tetrazines yield monoadducts possessing a diaryldihydropyridazine function nested atop the fullerene. The diaryldihydropyridazine functions direct a completely regioselective 1,4-hydrogenation, resulting in a racemic mixture of bifunctional bisadduct (+/-)-3.
