Electrogeneration and Structural Discussion of 6-Benzyl-3,5diphenylhydroxypyranones.-The cathodic reduction of 2-chloro-2phenacetyl chloride (I) at low current density yields the γ-pyrone derivative (II) whereas at high current density a mixture of the α-and γ-pyrones ( III) and (IV) together with a trace of dibenzyl ketone (V) is obtained. -(LOZANO,
