Trichloroacetyl chloride → HCID 86750013, compound

Participants

Reaction Steps

(Tolyl)diphenylsulphonium hexafluorophosphate (1.08 g, 2.57 mol) is dissolved in methanol (40 ml) with cooling in an ice-water bath. Sodium peroxide (2.42 g, 31 mmol) is added slowly. After 15 mins a solution of trichloro- acetyl chloride (1.4 ml, 12.5 mol) in methanol (30 ml) is added over 20 mins. After a further 30 mins the reaction mixture is filtered under vacuum and the filtrate evaporated in vacuo. Water is added and the resulting solid collected, washed with water and ether to give (tolyl)diphenylsulphoxonium hexafluorophosphate (0.72 g, 64% ) with spectra identical to those of authentic material.
