What is Phenylpropiolic acid?

Chemical properties

WHITE TO SLIGHTLY BEIGE FINE CRYSTALLINE POWDER

The Uses of Phenylpropiolic acid

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.

Definition

ChEBI: An acetylenic compound that is propynoic acid in which the acetylenic hydrogen is replaced by a phenyl group.

Purification Methods

Crystallise the acid from *benzene, CCl4 (m 136o) or aqueous EtOH. The S-benzylisothiuronium salt has m 184-186o (from EtOH). [Beilstein 9 II 436, 9 III 3061, 9 IV 2327.]
