Hess, U. published the artcileSynthesis of 4-aryl-1λ2,2λ4-dithia-3,4-diaza-buta-1,2-dienes, a new dithiadiazabutadiene system, Application of 4-Amino-2,6-dichlorobenzoic acid, the publication is Pharmazie (1994), 49(2-3), 121-5, database is CAplus and MEDLINE.
4-Aryl-1λ2,2λ4-dithia-3,4-diaza-buta-1,2-dienes, e.g. 2-O2NC6H4NHN:S:S, as representatives of a dithiadiazabutadiene structure in which sulfur occupies a different oxidation number are synthesized by reaction of diazotated acceptor-substituted aryl- and hetarylamines with thiosulfates or disodium disulfide in strong acid solution For some examples a first pharmacol. test indicate an immune-stimulating effect. Anal. examination as well as as MNDO calculation which give some mechanistical insight, supplements the new synthesis.
