General reaction conditions: 4-chlorotoluene (0.1 mmol, 1 equiv.), benzene (11.24 mmol, 112.4 equiv.), room temperature (air cooling), N2 atmosphere (balloon pressure), and UV light irradiation (254 nm, 10 mW·cm−2, 24 h). Isolated yield by silica gel column chromatography. Ratios of the regioisomers were determined by NMR. Aniline (11.0 mmol, 110 equiv.). Cyclohexylamine (8.77 mmol, 87.7 equiv.). Acetonitrile (1 mL), p-methoxyaniline (1 mmol, 10 equiv.). |
