Copper is king! A convenient method for the synthesis of trifluoromethylated heteroaromaticcompounds under mild conditions has been developed based on the observation that 1 can be reduced by certain metals (see scheme). Substrate 1 is assumed to be reduced by copper via a single‐electron transfer mechanism, and CuCF3 is the most probable intermediate in this reaction. DMF=N,N‐dimethylformamide, Tf=triflate
“Dance reaction” on the aromatic ring is a powerful method in organic chemistry to translocate functional groups on arene scaffolds. Notably, dance reactions of halides and pseudohalides offer a unique platform for the divergent synthesis of substituted (hetero)aromatic compounds when combined with transition-metal-catalyzed coupling reactions. Herein, we report a tandemreaction of ester dance and
An organic light-emitting device includes: a first electrode; a second electrode facing the first electrode; and an organic layer including an emission layer between the first electrode and the second electrode. The emission layer includes at least one compound selected from carbazole-based compounds, and at least one compound selected from heterocyclic compounds as described in the detailed description.
