Dichloromethane → (4-Hydroxyphenyl)diphenylsulfonium chloride

Participants

Reaction Steps

To a methylene chloride solution of 20 g of the diphenyl-4-methoxyphenylsulfonium trifluoromethanesulfonate, 90 ml of a 1 M boron tribromide-methylene chloride solution was slowly dropwise added with stirring at room temperature, and the mixture was stirred at room temperature for 2 hours. To the reaction mixture formed, methanol and distilled water were slowly added, followed by drying under reduced pressure to obtain a white crystal compound. The white crystal compound was dissolved in methanol, and ion exchange was effected using an anionic ion-exchange resin (Cl− type), followed by drying under reduced pressure to obtain 11.5 g of diphenyl-4-hydroxyphenylsulfonium chloride.
