Regioselective Oxygenative Tetraamination of [60]Fullerene. Fullerene-mediated Reduction of Molecular Oxygen by Amine via Ground State Single Electron Transfer in Dimethyl Sulfoxide
temperature and affords a variety of functionalized fullerene derivatives. Near-infrared analysis of a mixture of [60]fullerene and piperidine in a deaerated dimethyl sulfoxide/chlorobenzene mixture indicated equilibrium formation of [60]fullerene radical anion (C60•-) that persists at least for 2 weeks at room temperature but reacts immediately with molecular oxygen to give the tetraaminofullerene expoxide

N-methylpiperazine and N-(tert-butoxycarbonyl)piperazine were found to have low selectivity due to different side reactions. Tetraaminofullerene derivative C60(N-(2-pyridyl)piperazine)4O was found to react readily with organic and inorganic acids to yield highly water-soluble salts (solubility approximately 150 mg mL(-1)). In contrast, C60(N-(2-pyrimidinyl)piperazine)4O undergoes hydrolysis under the same conditions

Three new crystalline compounds of Ag(I) with fullerene-containing ligands, the piperidine adduct [C60(N(CH2CH2)2N)] and the fullero[60]pyrrolidine [C60(CH2N(CH3)CH2)], have been prepared and characterized by X-ray crystallography. The polymeric structure of [C60(N(CH2CH2)2N)][Ag(O2CCF3)]2}·CS2 consists of linear chains composed of two distinct molecules of the functionalized fullerene, with four

A range of fullerene monoadducts can be generated via the photochemical reaction of piperazine derivatives with C60. Addend functionality can also be efficiently incorporated by transformation of the hydroxyl-substituted adduct prepared in this fashion. Reaction yields and process simplicity compete with current standard procedures for fullerene mono-functionalisation.

Addends based on C2-substituted piperazine are employed to generate C60 monoadducts by photochemical addition, representing the first introduction of non-hydrocarbon addend functionality to fullerenes via the oxidative dehydrogenation reaction of diamines with fullerenes.
