An ortho-selective C-F bond borylation between N-heterocycle-substituted polyfluoroarenes and Bpin-Bpin with simple and commercially available [Rh(cod)2 ]BF4 as a catalyst is now reported. The reaction proceeds under mild reaction conditions with high efficiency and broad substrate scope, even toward monofluoroarene, thus providing a facile access to a wide(More)
An efficient and general method for the synthesis of difluoroalkylated phenanthridine derivatives through palladium-catalyzed reaction of difluoroalkyl bromides with isocyanides is described. The reaction can also be extended to perfluoroalkyl iodides. Mechanistic studies reveal that a difluoroalkyl radical via a single-electron-transfer pathway is involved(More)
A nickel-catalyzed three-component reaction for the synthesis of difluoroalkylated compounds through tandem difluoroalkylation-arylation of enamides has been developed. The reaction tolerates a variety of arylboronic acids and widely available difluoroalkyl bromides, and even the relatively inert substrate chlorodifluoroacetate. The significant advantages(More)
An efficient and synthetically convenient method for the synthesis of 3,3-difluoro-2-oxindole through a visible-light-induced photoredox difluoromethylation-amidation is described. The process can generate a broad range of difluorooxindoles using bromodifluoroacetate and broadly available free anilines. The wide range of substrate tolerance and mild(More)
An efficient palladium-catalyzed Heck-type reaction of fluoroalkyl halides, including perfluoroalkyl bromides, trifluoromethyl iodides, and difluoroalkyl bromides, has been developed. The reaction proceeds under mild reaction conditions with high efficiency and broad substrate scope, and provides a general and straightforward access to fluoroalkylated(More)
