The inter- and intramolecularaddition of free radicals onto ketenimines is studied. All the attempts to add intermolecularly several silicon, oxygen or carbon centered radicals to N-(4-methylphenyl)-C,C-diphenyl ketenimine were unsuccessful. In contrast, the intramolecularaddition of benzylic radicals, generated from xanthates, onto the central carbon of a ketenimine function with its N atom linked
