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
