For the first time, the reaction of fullerenyl azide with terminal acetylenes has been used to synthesize previously undescribed 1-butyl-2-triazolylfullerenes, in which the heterocyclic fragment is directly attached to the fullerene backbone. Water-soluble complexes of the synthesized adducts of fullerene with polyvinylpyrrolidone showed high cytotoxic activity towards tumor cells of the Jurkat, K562, U937 lines.
