to intramolecularhydrogenabstraction. Methyl N-(ω-phenylalkyl) carbanyl radicals and methyl N-pentylcarbamyi radicals readily abstract hydrogen through a six membered transition state or a seven membered transition state if the hydrogen is beniylic. The selectivities are interpreted in terms of the electrophilicity of the radical and the stereo-electronic requirements of hydrogenabstraction reactions
