We reported the decarboxylative coupling of alkynyl carboxylic acids and aryl halides using a palladium catalyst, which provides an efficient method for the synthesis of unsymmetrical and symmetrical diaryl alkynes. Aryl alkynes are important building blocks in the preparation of pharmaceutical and conjugated functional materials. The employment of alkynyl carboxylic acids as an alternative to terminal alkynes provides a very useful tool in the handling of alkynes with a low boiling point. Since we first reported the decarboxylative coupling reactions, a variety of such reactions involving alkynyl carboxylic acids have been reported by many research groups. Herein, we discuss a number of coupling reactions which are related to the decarboxylative couplings of propiolic acids including the selective coupling reaction, the multicomponent reactions and the carbonylations.
