Application
TCI Practical Example: TEMPO Oxidation Utilizing Iodobenzene Diacetate as a Reoxidant
-
Used Chemicals
-
Procedure
-
To a solution of 1-naphthalenemethanol (306 mg, 2.0 mmol) in dichloromethane (2 mL, 1.0 mol/L) was added TEMPO (31.2 mg, 0.20 mmol), PhI(OAc)2 (709mg, 2.2 mmol) and the mixture was stirred at room temperature for 4 hours. Dichloromethane (12.5 mL), saturated aqueous sodium thiosulfate solution (12.5 mL) was added and the mixture was stirred for 30 minutes. The organic layer was washed with saturated aqueous sodium bicarbonate solution (10 mL), brine (10 mL) and the organic layer was dried over sodium sulfate and filtered. The solvent was removed under reduced pressure and the residue was purified by column chromatography (ethyl acetate:hexane = 0:100 - 3:97 on silica gel) to give 1-naphthaldehyde as a yellow liquid (291 mg, 93%).

Application
Nitroxyl-radical-catalyzed Oxidative Coupling of Amides with Silylated Nucleophiles
Typical Procedure:
To a solution of N-benzylbenzenesulfonamide (61.8 mg, 0.25 mmol), KBr (14.9 mg, 0.125 mmol), and Na2SO4 (71.0 mg, 0.50 mmol) in MeCN (1.5 mL) is added t-BuOCl (33.9 µL, 0.30 mmol) at room temperature, and the mixture is stirred at room temperature for 1 h. Then, TEMPO (7.8 mg, 0.050 mmol) is added and stirred at room temperature for 30 min. To the solution is added Na2CO3 (26.5 mg, 0.25 mmol), and the mixture is stirred at room temperature for 20 h. Subsequently, TMSCN (93.8 mL, 0.75 mmol) and LiClO4 (2.7 mg, 0.025 mmol) are added to the reaction mixture, and further stirred at room temperature for 22 h. Saturated Na2SO3 aqueous solution (10 mL) is added to the mixture, and the product is extracted with AcOEt (15 mL×3). The organic phase is washed with brine and dried over Na2SO4. The organic phase is concentrated under reduced pressure, and the crude product is purified by column chromatography (hexane : AcOEt = 3 : 1) to give the desired product (67.4 mg, Y. 99%).
