应用
3-Buten-2-one can undergo conjugate addition with methanol over the solid base catalysts to afford 4-methoxy-butan-2-one. It can also undergo coupling reaction with alkyltins and alkynes in the presence of a nickel complex to form stereo-defined conjugated enynes.

Palladium-catalyzed heterocyclization-coupling sequences have been developed starting from buta-1,2,3-trienyl carbinols and electron-deficient alkenes. Polysubstituted furans are formed where the heterocyclic ring originates from the elements of the butatrienyl carbinol while the electron-deficient olefin is incorporated as a C-3 substituent. In
