General description
1-Penten-3-one also known as Ethyl vinyl ketone, is a straight-chain aliphatic α, β -unsaturated ketone, commonly used in the coupling reaction for the synthesis of diene and six-membered ring compounds.
Application
Reagent for annulation.
1-Penten-3-one can be used as a reactant to synthesize:
- Conjugated dienes via palladium-catalyzed Heck reaction with vinyl bromides.
- β-Amino carbonyl derivatives via solvent-free aza-Michael addition reaction with aromatic amines in the presence of ionic liquid catalyst.
- α-Exo-methylene group bearing β-amino carbonyl compounds via ion-supported triphenylphosphine catalyzed aza‐Morita‐Baylis-Hillman reaction with N-tosyl arylimines.
Disclaimer
Supply conditions do not apply to the regions and states of Brazil: North, Northeast, Mato Grosso do Sul, Mato Grosso, and Rio Grande do Sul.

The National Toxicology Program is conducting a chemical class study to investigate the structure-activity relationships for the toxicity of alpha,beta-unsaturated ketones. Ethyl vinyl ketone (EVK) was selected for study because it is a representative straight-chain aliphatic alpha,beta-unsaturated ketone with extensive
