Sir. a-Aryl and a-vinyl carbonyl groupings are structural features of a large number of biologically important molecules. A method for the direct arylation or vinylation of enolate anions would greatly simplify the synthesis of such molecules. Progress to this goal has been reported by a number of workers,'with perhaps the most promising approach to date being the trapping of photogenerated aryl radicals with ketone enolates (the SRN~ ...
