WitrynaAbstract. The replacement of a β-hydrogen on an α,β-unsaturated carbonyl system with a non-hydrogen, non-carbon atom amounts to either a net two electron oxidation or an isohypsic substitution at the β-carbon. The resulting compounds are the functional equivalents of β-dicarbonyl derivatives. Although many methods have been …
