Participants

Reaction Steps

75 g (0.55 mol) of trifluoromethylsulphenyl chloride are added at 20 to 25° C. with stirring to a solution of 43 g (0.2 mol) of 3-chloropropyl-2,4-difluorophenyl ketone in 100 ml of methylene chloride. The mixture is stirred at room temperature for 108 hours and then concentrated by stripping off the solvent under reduced pressure. 63 g of (3-chloro-1-trifluoromethylmercapto-propyl)-2,4-difluorophenyl ketone are obtained.
