Triphenylsulfonium chloride → Triphenylsulfonium hydroxycarbonyldifluoromethanesulfonate

참여 물질

반응 단계

Into 2036 parts of 11.2% aqueous triphenylsulfonium chloride solution, 859 parts of 17.6% aqueous sodium difluorosulfoacetate solution was added and the resultant mixture was stirred at 25° C. for about 20 hours. The mixture was filtered to obtain white solid and white solid obtained was washed with 150 parts of ion-exchanged water. 506 Parts of tert-butyl methyl ether was added to white solid obtained. The resultant mixture was stirred and filtered to obtain solid. The solid obtained was dried to obtain 246.9 parts of triphenylsulfonium hydroxycarbonyldifluoromethanesulfonate, which is called as TPS-1.
