It's low-boiling, flammable and unpleasant to smell, but t h e versatility of this low-molecular-weight aldehyde extends from beta-valerolactone with ketene to acrylonitrile with ammonia.

With its conjugated double bond, this crotonic ester will get a rise out of those looking for new dienophiles for Diels-Alder reactions. Eastman Chemical Products, Inc. Kingsport, Tennessee
