TCI Practical Example: Reduction of Ketone Using Sodium Borohydride

Used Chemicals

Procedure

Sodium borohydride (250 mg, 6.70 mmol) was separately added to a solution of 4',5'-dimethoxy-2'-nitroacetophenone (1.50 g, 6.70 mmol) in THF (12 mL) and methanol (3 mL) at 0 °C. Then the mixture was allowed to warm to room temperature and stirred for 1.5 hours. The solution was diluted with dichloromethane (15 mL) and washed with water (15 mL x 3) and brine (15 mL), dried over sodium sulfate and filtered. The solvent was removed under reduced pressure. The residue was diluted with THF (6 mL) and the mixture was stirred at 37 °C. Hexane (10 mL) was added to the solution and the mixture was stirred at 0 °C and filtered to give 1 (1.16 g、77%) as a yellow solid.

Experimenter’s Comments

The reaction mixture was monitored by TLC (hexane:ethyl acetate = 1:1, Rf = 0.47) and UPLC.
To avoid moisture absorption of sodium borohydride, weighing was done quickly.

Application
Nickel boride mediated cleavage of 1,3-dithiolanes

Typical procedure: 2,2-Diphenyl-1,3-dithiolane (0.2 g) dissolved in methanol (8 mL) and THF (2 mL). NiCl2·6H2O (0.92 g) is added, followed by NaBH4 (0.44 g). The reaction mixture is stirred vigorously at room temperature for 20 min. The reaction mixture was filtered through a celite pad and washed with methanol (2 x 10 mL). Water is added to the filtrate, which is extracted with ethyl acetate (3 x 10 mL). The combined extract is dried over MgSO4, and concentrated under reduced pressure to give diphenylmethane (0.12g, 92 %).
