This article describes the copper-catalyzed oxidative trifluoromethylation of heteroarenes and highly electron-deficient arenes with CF(3)SiMe(3) through directC-H activation. In the presence of catalyst Cu(OAc)(2), ligand 1,10-phenanthroline and cobases tert-BuONa/NaOAc, oxidative trifluoromethylation of 1,3,4-oxadiazoles with CF(3)SiMe(3) proceeded smoothly using either air or di-tert-butyl peroxide

We disclose a Bi-catalyzed C–H trifluoromethylation of (hetero)arenes using CF3SO2Cl under light irradiation. The catalytic method permits the direct functionalization of various heterocycles bearing distinct functional groups. The structural and computational studies suggest that the process occurs through an open-shell redox manifold at bismuth, comprising three unusual elementary steps for a main
Direct C2-selective trifluoromethylation of indole derivatives was achieved with Togni's hypervalent iodine reagent and CuOAc as a catalyst in MeOH under mild conditions, affording the desired C2-trifluoromethylated indoles in good yield (up to 90%). (C) 2010 Elsevier Ltd. All rights reserved.
