The dienone-dianion derivatives 1 react with all types of electrophiles tested (alkyl halide, silyl chloride, ester, ketone, aldehyde, epoxide) to give β,υ-unsaturated carbonyl compounds of type A (see Formulae 2-6, 13, 14 and Tables 1-5).The α- and β-hyd

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
