Abstract

Simple transition-metal salts were investigated as the catalysts for the partial oxidation of methane. In trifluoroacetic acid (TFA), methane could be efficiently converted to methyl trifluoroacetate by the Cu(OAc)₂/K₂S₂O₈ catalyst system. A quantitative yield (96.3%) based on methane has been obtained under the optimized conditions. A possible mechanism involving radical intermediates has been suggested for this reaction.

Abstract

Achieving p-C_Ar–H site selectivity is one of the major challenges in direct carbon–hydrogen (C–H) functionalization reactions. Herein, the copper-catalyzed and picolinamide-assisted remote p-C–H sulfonylation of 1-naphthylamides was realized. The synthetic utility of this method was further examined by sequential functionalizations and the efficient synthesis of the pharmaceutically useful 5-HT₆ serotonin receptor ligand. This approach also provided a general strategy for other p-C–H bond functionalization, such as highly selective constructions of C–O, C–Br, C–I, C–C, and C–N bonds. Control experiments and theoretical calculations suggested that this C–H sulfonylation reaction might proceed through a single-electron-transfer process.
