The reaction of 2-phenylimino- and 2-(p-tolylimino)thiazolidin-4-ones with benzene-, p-nitrobenzene, p-sulfamoylbenzene-, and p-toluenediazonium chlorides in glacial acetic acid in the presence of anhydrous sodium acetate (pH of the medium 4.5–5.0) has been studied. A spectroscopic investigation in the IR and UV regions has shown that the 5-(p-nitrophenylazo) derivatives of thiazolidin-4-one exist in the azo tautomeric form; the 5-phenylazo and p-tolylazo derivatives of thiazolidin-4-one are mixtures of the azo and hydrazone tautomers.
