Manganese-catalyzed Aerobic Oxytrifluoromethylation of Styrene Derivatives
Typical Procedure:
To a solution of CF3SO2Na (128 mg, 0.8 mmol) in acetone (4 mL) are added styrenes (0.4 mmol) and then MnCl2·4H2O (16 mg, 0.08 mmol). The reaction mixture is stirred vigorously under an open atmosphere at room temperature for 12－48 h until the styrene substrate disappears by TLC monitoring. After completion of the reaction, the reaction mixture is poured into 5% aqueous NaHCO3 solution (20 mL) and then is diluted with ether (20 mL) and filtered through Celite. The filtrate is separated, and the aqueous layer is extracted by ether (20 mL). The organic phase is washed with saturated NaCl aqueous solution and then dried over sodium sulfate. After removal of the solvent in vacuo, the residue is purified by flash chromatography (hexane : ethyl acetate = 20 : 1 to 8 : 1) on silica gel to afford the corresponding ketone and alcohol products, respectively.
