α,β-Unsaturated carbonyl compound

特許 係属中 α,β-Unsaturated carbonyl compounds are an important class of carbonyl compounds with the general structure −(O=C)−Cα=Cβ−. In these compounds the carbonyl group is conjugated with an alkene (hence the adjective unsaturated), from which they derive special properties. Unlike the case for simple carbonyls, α,β-unsaturated carbonyl compounds are often attacked by nucleophiles at the β carbon.
