On treatment of 1-amino-1-alkyl-3-arylguanidines with thionyl chloride in pyridine, yellow complexes between mesoionic 1,2,3,5-thiatriazoles (anhydro-3-alkyl-4-arylamino-1,2,3,5-thiatriazolium hydroxides) and pyridinium chloride are formed.The strongly coloured mesoionic compounds are liberated by treatment with base (aryl = phenyl, 4-methylphenyl, 2-chlorophenyl; alkyl = methyl).On attempted synthesis of 5-phenyl-1,2,3,5-thiatriazole by treatment of benzamidrazone with thionyl chloride in pyridine, spontaneous evolution of nitrogen and formation of benzonitrile and sulfur were observed.
