Description and Uses
Phenylpropiolic Acid is used as a reagent in the high yield synthesis of 3,3-diphenylpropanoic acid derivatives via hydrophenylation and ionic hydrogenation with strong Lewis acids. It is also used in the synthesis of highly substituted aromatic rings via the alkyne-mediated approach which serve as templates for drug design.
