N-acetyl-N-trichloromethylsulphenylarenesulphonamides

Abstract

In a search for new fungicides, N-acetyl-N-trichloromethylsulphenylbenzenesulphonamide and the following derivatives have been prepared: p-methyl, p-chloro, o-nitro, p-ethoxy, p-acetamido, p-methoxy, 2,5-dimethoxy, p-phenylazo, 3-bromo-4-methoxy, 5-bromo-2-methoxy, 5-chloro-2-methoxy, 4-chloro-3-nitro, 2,3,4-trichloro, 4-chloro-3-methyl, and 2-chloro-5-methyl. These compounds were synthesised by condensation of trichloromethanesulphenyl chloride with the appropriate N-acetylarenesulphonamide; this reaction and the formation of the N-acetylsulphonamides are briefly discussed.
