MONO-FUNCTIONALIZATION AND BISFUNCTIONALIZATION OF FULLERENES WITH N-CONTAINING REACTANTS

The thermolysis of sulfonyl azides in the presence of fullerenes leads to azafulleroids with a 1,6-opened structure. The corresponding 1,2-c losed aziridinofullerenes are obtained from the azafulleroids by irrad iation, probably via a di-pi-methane rearrangement. The photoreactions of 4-methyl-1,2,4-triazoline-3,5-dione (NMTAD) with two isomeric [60] fullerene-derivatives have been studied. In both cases the formation o f the same cycloadduct is observed which indicates that at a certain s tage rearrangements must be involved.
