(A) Electrophotocatalytic C–H/N–H coupling of benzene and pyrazole 4. (B) 1H NMR spectra of (1) the reaction shown in Figure 2A; (2) the same conditions without catalyst 1 showing no reaction occurred; (3) the same reaction under direct electrolysis at 3.0 V; and (4) direct electrolysis of benzene at 3.0 V. (C) Visual comparison of attempted direct electrolysis and electrophotocatalytic reactions.
