Efficient and Mild Synthesis of Novel Diazo Dyes through Coupling Reaction of Schiff Base Diazonium Salts with β-naphthol

Abstract

In this study, efficient and mild method for synthesis of some novel diazo dyes containing Schiff bases has been reported. All of the intermediates and final products were obtained in good to high yields and appropriate reaction times. The structures of desired products were determined using physical and spectroscopy data such as; IR, 1H NMR, 13C NMR, mass spectra, and C.H.N. analyses. The worldwide availability, larger scale synthesis, high yields, and short reaction times are the advantages of the present method.
