Alkylation and phenylation of [60]- and [70]-fullerenes by the reaction with ketones in the ionization chamber of a mass spectrometer

The title reactions proceed under electron impact (EI) and are accompanied by hydrogen addition and loss; the reaction of C₆₀ with acetone has been shown to occur at least partly at the walls of the ionization chamber and experimental evidence suggests a radical path process involving EI generation of methyl radicals from acetone
