Application

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.

Conjugated Type-2 alkenes, such as acrylamide (ACR), are soft electrophiles that produce neurotoxicity by forming adducts with soft nucleophilic sulfhydryl groups on proteins. Soft-soft interactions are governed by frontier molecular orbital characteristics and can be defined by quantum mechanical parameters
