Michael Addition Reaction of Thioacetic Acid (AcSH) to Conjugated Alkenes Under Solvent- and Catalyst-Free Conditions

A new and convenient procedure has been developed for the Michael addition reaction of thioacetic acid (AcSH) to a variety of conjugated alkenes under solvent- and catalyst-free conditions. These reactions proceeded in 5-60 min and produced the desired products in good to high yields.
