3-Chlorobenzoic Acid → HCID 21393535, compound

Participants

Reaction Steps

To a solution of 2.55g. (0.01 mole) of 2-methyl-4,4,5,5-tetrachloro-3-isothiazolidinone in 10 ml. of chloroform at 0° is added a solution of 2.03g. (0.01 mole) of m-chloroperbenzoic acid (85% Technical) in 60 ml. of chloroform. The mixture is allowed to warm to room temperature and stand over a weekend. The solution is cooled in dry ice. White solid (m-chlorobenzoic acid) separates (0.91g.) and is removed by filtration. The filtrate is washed in a separatory funnel with 50 ml. of water containing 0.4g. of sodium bicarbonate. The chloroform solution is separated and dried over magnesium sulfate. Evaporation gives 2.54g. of crude product as a white solid.
