Synthesis and Spectroscopic Studies on Some Dyes of the Type Dihydrazono 2-cyanomethyl-2-thiazolin-4-one

Several new dihydrazono-2-thiazolin-4-one dyes 6a-j are synthesized in excellent yields via coupling of 2-cyanomethyl-2-thiazolin-4-one 1 with diazotised aromatic amines in excess pyridine.Proofs of structures based on microanalytical and spectroscopic data are given and discussed.Electronic absorption spectra of the so synthesized dyes are studied in aqueous buffer solutions of varying pH, and their dissociation constants pK are determined spectrophotometrically.
