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.
