설명

일반 설명

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.

애플리케이션

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.

Reagent for annulation.
