The coupling of a difluoroallylboronate with aryl and heteroaryl halides and triflates provides a convenient and broadly applicable synthesis of difluoroallylarenes. The difluoroallyl boron reagent is formed by a copper-catalyzed defluorinative borylation of the inexpensive reagent 3,3,3-trifluoropropene, and the products undergo a wide range of reactions to a series of difluoro-substituted analogs of common biologically valuable building blocks.
