cross-coupling of polyfluorinated arenes with a broad range of aryl halides has been developed. Sequential carbon-fluorine bond cleavage and carbon-carbonbondformation are two of the important features of the reaction. Addition of an arylradical anion to a nickel intermediate was achieved for the first time using polyfluoroarenes as radical precursors. This, in combination with the excellent para selectivity
The present invention is a one-step method for efficiently converting carbon-hydrogen bonds into carbon-carbon bonds using a combination of aryl halides, a substrate, and a copper salt as catalyst. This method allows faster introduction of complex molecular entities, a process that would otherwise require many more steps. This invention is particularly relevant for the organic synthesis of complex molecules such as, but not limited to, pharmacophores and explosives.

cross-coupling reaction of arenediazonium tetrafluoroborates with polyfluoroarenes is briefly described. It has advantages of high reaction efficiency, excellent functional group compatibility, mild reaction conditions, short reaction time, and inexpensive ligand. This reaction also can be performed as a one-pot process from anilines omitting isolation of arenediazonium tetrafluoroborates. It has been
