  Copper-catalyzed fluoroalkylation of alkynes and alkynyl carboxylic acids has been achieved with high functional-group tolerance and excellent regio- and stereoselectivities. A variety of fluoroalkyl halides including ethyl bromodifluoroacetate can be employed. Additionally, an unprecedented decarboxylative fluoroalkylation of α, β-unsaturated carboxylic acids has been achieved via a radical pathway.

  synthesis of pentafluoroethyl copper (CuC2F5) from a cuprate reagent and ethyl pentafluoropropionate as one of the most economical and useful pentafluoroethyl sources was accomplished. The advantages of this method are; all the reagents employed are low-cost and operationally simple, and the CuC2F5 reagent is prepared in virtually quantitative yield. Furthermore, the CuC2F5 reagent prepared was successfully

  Introduction of the trifluoromethyl (CF3) group into organic compounds has garnered substantial interest because of its significant role in pharmaceuticals and agrochemicals. Here, we report a hydroxylamine‐mediated radical process for C(sp2)−H trifluoromethylation of terminal alkenes. The reaction shows good reactivity, impressive E/Z selectivity (up to > 20:1), and broad functional group compatibility. Expansion of this approach to perfluoroalkylation and late‐stage trifluoromethylation of bioactive molecules demonstrates its promising application potential. Mechanistic studies suggest that the reaction follows a radical addition and subsequent elimination pathway.
