✦ Synopsis

Ultraviolet irradiation of the title compounds in amine solvents results in transformations attributed to initial formation of radical ions by electron transfer, the quantum efficiency of reaction depending on the ionization potential of the amine. Cross-conjugated cyclohexadienones have been the subject of intensive photochemical investigation for many years.' In this laboratory, dienones la and lb have been shown to --
