Benzophenone is photoreduced by phtalimidines and dihydro isoquinolones.The hydrogen atom α to the nitrogen atom is abstracted and radical coupling leads to adducts.CIDNP studies of these adducts show inversion of polarisation for the adduct on the N-alkyl chain when the nitrogen is bound to a benzylic methylene.This inversion is explained by considering that the radical on the N-alkyl chain derives from the radical on the ring.
