4-Toluenesulfonyl chloride → HCID 86750013, compound

Participants

Reaction Steps

(Tolyl)diphenylsulphonium hexafluorophosphate (1.08 g, 2.57 mmol) is dissolved with stirring in acetonitrile (40 ml). The resulting solution is stirred while p-toluene- sulphonyl chloride (2.38 g, 12.5 mmol) added. The reaction mixture is cooled in an ice-water bath. A solution of sodium peroxide (2.42 g, 31 mmol) in water (30 ml) is added dropwise over 20 minutes. After a further 2 hours the reaction mixture is filtered under vacuum and the filtrate evaporated in vacuo. Water is added and the resulting solid collected, and washed with water and ether to give (tolyl)diphenylsulphoxonium hexafluorophosphate (0.63 g, 56%) with spectra identical to authentic material.
