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 C-60 with acetone has been s hown to occur at least partly at the walls of the ionization chamber and ex perimental evidence suggests a radical path process involving EI generation of methyl radicals from acetone.
