A series of 1,4-benzoxathiin 4,4-dioxide derivatives have been prepared by a new synthetic route. The reactions of 2-chloro-4-nitrobenzenethiol 1 with 1 -aryl-2-chloroethanones 2 in the presence of sodium hydroxide give 1-aryl-2-(2-chloro-4-nitrophenylthio)ethanones 3 which on oxidation with \(30 \%
