GENERATION OF DIENONE AND TRIENONE DIANION DERIVATIVES; DOUBLE DEPROTONATION AS A ROUTE TO LUMO-FILLED ?-SYSTEMS
Conjugated unsaturated carbonyl compounds and their analogues 1 are a1,3,5...-reagents.An umpolung of this intrinsic reactivity can be achieved by generation of the dianions 2, LUMO filled ?-systems, from hydrogenated precursors, see schemes 1
