Abstract: | Several fulleroaziridines, azafulleroids and chiral cage-opened ketolactams were synthesized from alkyl azides and C60. Their solubility in various solvents was evaluated by HPLC. It depends both on the starting azide and the linker group. Moreover, the formation of two sp3 carbons (entries 2) and then of carbonyl derivatives (entries 3) induces a decrease of the polarizability of the C60 moiety and an enhancement of the solubility in lipophilic solvents. |
