2-(Trifluoromethoxy)chlorobenzene

Clear colorless to yellow liquid

General procedure: In a glovebox, to an oven-dried 20 mL screw cap vial was added 2- (3, 5-bis (trifluoromethyl) phenyl) -4-nitro-l- (trifluoromethoxy) -6- (trifluoromethyl) -lii-benzo [d] imidazole (1) (105 mg, 0.200 mmol, 1.00 equiv) , arene (2.00 mmol, 10.0 equiv) and Ru (bpy) 3 ( REe) 2, (0.0516 mg, 0.0600 pmol, 0.0300 moll) . Then MeCN (1.00 mL, 0.200 M) and a magnetic stir bar were added. The vial was capped and taken out of the glovebox. The reaction mixture was then stirred and irradiated with a 10 W LED (402 nm) at room temperature. After 16 h, an internal standard PhCF3 (5.84 mg, 4.95 pL, 0.04 mmol, 0.200 equiv) was added to the reaction vial, 0.200 mL of the resulting mixture was transferred to a 2 mL vial containing 0.500 mL of CDCI3. After the yield was determined using 19F NMR, the NMR sample was combined with the rest of the reaction mixture and the solvent was removed in vacuo. The crude material was purified by HPLC under noted conditions. The fractions containing the desired product were combined and extracted with CDCI3 (3 1 mL) , dried with magnesium sulfate, and filtered. The filtrate was concentrated in vacuo to furnish the desired product of trifluoromethoxylation . For volatile compounds, after purification by HPLC, the desired product was extracted with 1 mL CDC13 and then directly characterized. The NMR peaks are referring to CH3CN residue signal ^H-NMR: d 1.94, 13C~NMR: 5 118.26, 1.32).2General procedure: In a glovebox, to an oven-dried 20 mL screw cap vial was added 3- methyl-4-nitro-l- ( trifluoromethoxy) -6- (trifluoromethyl ) -1H- benzo[d] [1, 2, 3] triazol-3-ium trifluoromethanesulfonate (lb) (98.0 mg, 0.200 mmol, 1.00 equiv), arene (2.00 mmol, 10.0 equiv) and Ru (bpy) 3 (PFe) 2, (1.72 mg, 2.00 pmol, 1.00 mol%). Then MeCN (1.00 mL, 0.200 M) and a magnetic stir bar were added. The vial was capped and taken out of the glovebox. The reaction mixture was then stirred and irradiated with 2 of 10 W LED (Xmax = 447 nm) at room temperature. After 16 h, an internal standard PhCF3 (24.6 pL, 0.200 mmol, 1.00 equiv) was added to the reaction vial, 0.200 mL of the resulting mixture was transferred to a 2 mL vial containing 0.500 mL of CDC13. After the yield was determined using 19F NMR, the NMR sample was combined with the rest of the reaction mixture and the solvent was removed in vacuo. The crude material was purified by HPLC under noted conditions. The fractions containing the desired product were combined and extracted with CDC13 (3 x 10.0 mL) , dried with magnesium sulfate, and filtered unless otherwise noted. The filtrate was concentrated in vacuo to furnish the desired product of trifluoromethoxylation . For volatile compounds, after purification by HPLC, the desired product was extracted with 1 mL CDCI3 and then directly characterized. The NMR peaks are referring to CCN residue signal (1H-NMR : d 1.94, 13C-NMR: d 118.26, 1.32).2
