THE PHOTOCHEMICAL PRODUCTION OF STRAINED RINGS.
Abstract
The object of the research was the photochemical synthesis of rings. It was found that intermolecular cycloaddition, a previously unknown phenomenon outside dimerization, could be induced photochemically. Whilst simple unsaturated ketones appeared unreactive the hydrogen bonded 'cyclic' ketone acetyl acetone could be induced to participate. Further, this diketone had the advantage that any hydrogen abstraction would give a diradical which would be immediately converted, by spin inversion, into the starting material. Two other unrelated photochemical studies are also reported: (1) the photosensitized oxidation of pyrrole, providing the structure of the product maleimide and the mechanism of oxidation; and (2) the dimerization of alpha-pyridones and sultones as a means of building cyclic systems.
