Participants

Reaction Steps

The solution of 4-phenylsulfanyl-benzaldehyde (0.2 g, 0.93 mmol) in acetone (10 mL) was cooled to 0° C. in an ice bath. A solution of sulfamic acid (0.272 g, 2.8 mmol) in water (1 mL) was added and allowed to stir for 5 minutes at same temperature. An aq. solution of sodium chlorite (0.338 g, 3.7 mmol in 1 mL) was added and thew reaction mixture was allowed to stir for 30 minutes. The progress of the reaction was monitored by TLC. The reaction mixture was diluted with water and the resulting precipitate was filtered, washed with water and dried to get the title compound.
