A Our design of methylating reagent. Nucleophilicity index, ω-, in eV is computed by B3LYP/6-311 + g(d,p). QN-H+, quinolinium. B Reaction development. See the Supplementary Information for detailed conditions. General conditions: heteroarene (1.0 equiv), R1 (1.5 equiv), 12 h. Unless otherwise specified, the yield refers to the calibrated yields using gas chromatography (GC) or nuclear magnetic resonance (NMR) spectroscopy with internal standards. Iso., isolation. Abs, absorption. Emis, emission. LED, light-emitting diode. AcOH, acetic acid. TFA, trifluoroacetic acid. MsOH, methanesulfonic acid. TFAA, trifluoroacetic acid anhydride. DCM, dichloromethane. DCE, 1,2-dichloroethane. TFE, 2,2,2-trifluoroethanol. DMSO, dimethylsulfoxide. DMF, N,N-dimethylformamide. DMA, N,N-dimethylacetamide. Low/high C, low/high concentration (0.10/0.025 M). Low/high I, low/high light intensity (23/100 W). High T, high reaction temperature (~ 60 °C).
