Irradiation of N-alkyl-5-phenyl-4-penten-1-amines results in the formation of intramolecular styrene-amine adducts and disproportionation products. Increasing the bulk of the N-alkyl group increases the regioselectivity of N-H transfer favoring the formation of piperidine vs. pyrrolidine products and favors disproportionation vs. cyclization.
