2propenoyl

2propenoyl is a chemical group with the formula CH2=CHCO-. It is derived from acrylic acid by the removal of the hydroxyl group. This acyl group is characterized by a carbon-carbon double bond adjacent to a carbonyl group. This arrangement makes the 2propenoyl group highly reactive, particularly in addition polymerization reactions.

The 2propenoyl group is a fundamental building block in the synthesis of various polymers, most notably polyacrylates. When monomers containing the 2propenoyl group, such as acrylic acid or its esters, undergo polymerization, they link together to form long polymer chains. These polymers find widespread applications in industries such as coatings, adhesives, textiles, and plastics. The reactivity of the double bond allows for the formation of strong covalent bonds between monomer units, resulting in stable and versatile polymeric materials.

Compounds containing the 2propenoyl moiety are often referred to as acryloyl compounds. For instance, acryloyl chloride (CH2=CHCOCl) is a reactive derivative where the hydroxyl group of acrylic acid is replaced by a chlorine atom. These compounds are valuable intermediates in organic synthesis, enabling the introduction of the 2propenoyl group into other molecules. The presence of the electron-withdrawing carbonyl group activates the double bond towards nucleophilic attack, further contributing to its synthetic utility.
