| Abstract: | 6,7-Dimethylbenzimidazo2,1-b]thiazolid-3-one was synthesized, and its reactions with aldehydes, isatin, nitroso compounds, and arene diazonium salts were studied. As a result, ylidene and imino derivatives and azo coupling products were obtained. According to the IR spectra, the azo coupling products have 6,7-dimethylbenzimidazo2,1-b]thiazolidine-2,3-dione 2-arylhydrazone structures.See 1] for communication LVI.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, pp. 822–825, June, 1971. |
