General reaction conditions: trifluoromethanesulfonyl chloride (0.1 mmol, 1 equiv.), benzene (11.24 mmol, 112.4 equiv.), iodobenzene (8.93 mmol, 89.3 equiv.), toluene (9.43 mmol, 94.3 equiv.), anisole (9.2 mmol, 92 equiv.), benzonitrile (9.79 mmol, 97.9 equiv.), room temperature (air cooling), N2 atmosphere (balloon pressure), and UV light irradiation (254 nm, 10 mW·cm−2, 24 h); conversions were determined by 19F NMR with benzotrifluoride as an internal standard. |
