Flash vacuum pyrolysis studies of substitutedbenzyl, phenylaminyl, and phenoxylradicals have revealed three new classes of reactions: formation of five-membered ring products via intramolecular abstraction of an aromatic hydrogen atom, formation of six-membered rings via spirodienyl radical intermediates, and isomerisation of o-phenoxybenzyl into o-benzylphenoxyl radicals and vice versa.
