Application

Phenylpropiolic acid can:
  • React with 2-tert-butoxypyridine in the presence of boron trifluoride·diethyl etherate to form the corresponding tert-butyl ester.
  • Undergo decarboxylative coupling with aryl halides such as p-chloroiodobenzene and 1-chloro-4-iodobenzene.
  • Undergo halodecarboxylation to form 1-haloalkynes.

Z-2-(β-d-glucopyranosyloxy)-3-phenylpropenoic acid (PPAG), a compound postulated to contribute to the taste and mouthfeel of fermented rooibos tea (Aspalathus linearis), was isolated from unfermented rooibos plant material. Its structure was unequivocally confirmed by LC-MS, -MS(2), FT-IR and NMR of the underivatised
Palladium-catalyzed decarboxylative cross-coupling of alkynyl carboxylic acids with arylboronic acids.
