Nitrogen derivatives of C60 and C70: Interaction of fullerenes with nitrogen in gas phase and with amines in solution phase

Abstract

Mass spectrometric studies show that contact-arc vaporization of graphite in a partial atmosphere of N₂ or NH₃ yields nitrogenous products tentatively assigned to species such as C₇₀N₂, C₅₆N₆, C₅₉N₄ and C₅₉N₂ involving addition of or substitution by nitrogen along with the species due to C₂ and C₄ losses. Mass spectrometry and other techniques have been employed to identify products of the nucleophilic addition of aliphatic amines to C₆₀ and C₇₀ in solution phase.
