and ε-lithioketone equivalents. Primary and tertiary organolithiums have been generated and the ketone function may be part of a ring. The major synthetic use demonstrated in this report is the conversion to mixed heterocuprates which react with acyl chlorides to yield mono-protected 1,6- or 1,7-diketones. The cuprates also undergo conjugate addition to enones.
