It is shown that 'photochemically inert'α, β-unsaturated ketones can undergo synthetically useful uv light induced deconjugation via photoenolization in the presence of a mild base, and the mechanism of this reaction has been examined by measurement of the relative quantum yield of deconjugation as a function of base and solvent; the results indicate two competing mechanism for the reketonization of the intermediate dienols, one involving a ...
