Definition of Acryl group

An acrylic compound is typically an α,β-unsaturated carbonyl compound: it contains a carbon-carbon double bond and a carbon-oxygen double bond, separated by a carbon-carbon single bond. It has therefore the properties characteristic for both functional groups :

• at the C=C bond: electrophilic addition of acids and halogens, hydrogenation, hydroxylation and cleavage of the bond
• at the C=O bond: nucleophilic substitution (such as in esters) or nucleophilic addition (such as in ketones). The carboxyl group of acrylic acid can react with ammonia to form acrylamide, or with an alcohol to form an acrylate ester.
