Abstract

Para - substituted benzenesulphonamido - 1 : 3 : 4-thiodiazoles are prepared by reacting a para-substituted benzene sulphonyl halide with a thio-semicarbazone of an aliphatic aldehyde followed by oxidation. The para-substituted group on the benzene sulphonyl halide is either an acyl-amino-, nitro-, azo- or hydrazo-group. The condensation preferably takes place in a basic solvent such as pyridine. The preferred oxidizing agent for the final step is potassium ferricyanide. In an example, p-acetylaminobenzenesulphonyl chloride is added to a pyridine solution of acetaldehyde-thiosemicarbazone and the reaction product heated on the water bath. The condensation product thus obtained is oxidized with potassium ferricyanide in alkaline aqueous solution to give 2 - amino - benzenesulphonamido-5-methyl-1 : 3 : 4-thiodiazole.
