Abstract
The coupling of benzimidazolo[2′, 1′:2, 3]thiazolidin-4-one with benzenediazonium chlorides in acetic acid in the presence of sodium acetate at pH 4.5–4.0 has yielded 5-arylazo derivatives of the thiazolidone. By a study of the IR and UV spectra of the aryl derivatives of benzimidazolo[2′, 1′:2, 3]thiazolidin-4-one synthesized, it has been shown that the latter has the azo structure.
