o-Phenylenediamines react with sulphur monochloride forming 2,1,3-benzothiadiazoles. In acid solution the nitro-group of o-nitroanilines oxidises sulphur monochloride to thionyl chloride, and the phenylenediamine thus formed reacts with these sulphur compounds giving the corresponding benzothiadiazole.
