Trifluoromethylated acetylenes and arenes are widely applicable in the synthesis of pharmaceuticals and agrochemicals. In 2010, our group has reported the copper-mediated oxidative trifluomethylation of terminal alkynes and aryl boronic acids. This method allows a wide range of functional group tolerant trifluoromethylated acetylenes and arenes to be easily prepared. After the preliminary mechanistic studies of the oxidative trifluoromethylation of terminal alkyne, an efficient copper-catalyzed oxidative trifluoromethylation of terminal alkynes and aryl boronic acids has been developed. The catalytic protocol is successfully achieved by adding both the substrate and a portion of CF3TMS slowly using a syringe pump to the reaction mixture.

An efficient copper-mediated trifluoromethylation of terminal alkynes with nucleophilic trifluoromethylating reagent (Me3SiCF3) was developed. Both aromatic alkynes and aliphatic alkynes were effective, and a variety of functionalities such as amino, -OMe, -CO2Et, -Br, and -NO2 were tolerated under the reaction conditions. This reaction provides a general, straightforward, and practically useful method to prepare trifluoromethylated acetylenes.

1-Aryl- or 1-alkenyl-2-(perfluoroalkyl)acetylenes were produced in high yields by coupling reaction of aryl or alkenyl iodides with (perfluoroalkynyl)zinc compounds prepared from the corresponding (perfluoroalkyl)acetylenes in the presence of Pd catalyst.
