Thermal Diels−Alder reactions between C60 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.
