Abstract
The ratios of the ring-opened products formed on photolysis of certain monocyclic and bicyclic cyclopentanones and cyclohexanones in the presence of methanol are shown to be qualitatively consistent with the initial formation of a ring-opened diradical by an α-cleavage (Norrish type 1) mechanism followed by intramolecular hydrogen-transfer to give the primary photoproducts.Keywords
