Fig. 1. The transition metal-free C–H arylation of heteroarenes at room temperature. (a) The substrate scope for heteroarene arylation. (b) Large-scale synthesis of the core parts of bioactive molecules. (c) The C2 arylation of pyridine. aNMR conversion: t = 24 h for azole arylation and t = 8 h for furan and thiophene arylation.
