A palladium-catalyzed difluoromethylthiolation of heteroaryl halides and triflates under mild conditions was described. A vast range of heteroaryl halides such as pyridyl, quinolinyl, benzothiazolyl, thiophenyl, carbazolyl and pyazolyl halides could be difluoromethylthiolated efficiently, thus providing medicinal chemists with new tools for their search of new lead compounds for drug discovery.

reported an electrochemically mediated method for the preparation of 2,1-benzoxazoles from o-nitrophenylacetylenes. Different from the traditional electrochemical reduction of nitro to nitroso, the nitro group directly underwent a cyclization reaction with the alkyne activated by selenium cation generated by the anodic oxidation of diphenyldiselenide and finally produced the desired products.
or I, Q = PPh4) in copper-mediatedtrifluoromethylation of arylhalides were studied. Qualitative and quantitative studies showed [Cu(CF3)2]−Q+ and [Cu(CF3)(I)]−Q+ were not highly reactive. Instead, a much more reactive species, ligandless [CuCF3] or DMF-ligated species [(DMF)CuCF3], was generated in the presence of excess CuI. On the basis of these results, a general mechanistic map for CuI-promoted
disorders in both structures. The crystals of complex 1b exist as a mixture of two species, [Cu(CF3)(Cl)]− and [Cu(CF3)2]−, while the crystals of complex 1c are a mixture of three species, [Cu(CF3)(I)]−, [Cu(CF3)2]−, and [CuI2]−. The structures of complexes 1b and 1c were tentatively assigned as [Cu(CF3)(Cl)]− and [Cu(CF3)(I)]−, since the unit-cell parameters of the crystal lattices of [Cu(CF3)2]− and [CuI2]−
