Abstract

The present paper deals with the synthesis of thiazolo-coumarin derivatives, prepared starting from naphthaldehyde, ethyl acetoacetate and hydrazine in three steps and characterized by spectroscopic analysis. UV-Visible spectra of the compounds was carried out in different solvents DMF, ethanol, methanol, ethyl acetate and acetone and the absorption was observed in the range 338-390 nm. Electrochemical study of thiazoles was conducted in DMF and redox behavior was examined. Fluorescence carried out in ethanol showed sharp emission in the range 440-505 nm.
