Propiolic acid, known scientifically by its CAS number 471-25-0, is a vital component in the toolbox of synthetic chemists. As the simplest acetylenic carboxylic acid, its molecular structure—a triple bond adjacent to a carboxylic acid group—dictates its rich reaction chemistry. This unique arrangement facilitates participation in a wide array of transformations, making it a valuable precursor for numerous advanced organic compounds.

The chemical reactions of propiolic acid are diverse and enabling. It is frequently employed in palladium-catalyzed cross-coupling reactions, such as the Sonogashira coupling, where it reacts with terminal alkynes to form internal alkynes. Decarboxylative coupling reactions, in particular, allow for the efficient synthesis of diarylalkynes and diaryl alkynones, crucial structures in materials science and drug discovery. Its ability to undergo cycloaddition reactions further broadens its synthetic utility, enabling the construction of heterocyclic systems.

These chemical reactions are fundamental to its application in producing fine chemicals, pharmaceutical intermediates, and specialty materials. For example, the synthesis of transition metal complexes often utilizes propiolic acid derivatives. Its use as a reagent in forming haloalkyl propiolates highlights its versatility in introducing specific functional groups into molecules.
