The cathodic reduction of 2-chloro-2-phenylacetyl chloride in dichloromethanetetraethylammonium chloride on mercury cathode led to the formation of either a mixture of α- and γ-6-benzyl-3,5-diphenylhydroxypyranones or corresponding phenylacetate derivative of the latter depending on the conditions, in only one step. A study of these compounds solved the controversy which existed in the literature about the correct assignment of these structures.
