In the presence of Pd(OAc)2 and Xphos, alkynyl carboxylic acids smoothly underwent a decarboxylative coupling reaction with various benzyl halides or aryl halides, providing internal alkynes in good yields. It is noteworthy that the optimal conditions are compatible with a wide range of aryl halides.
