Synthesis and Spectroscopic Evaluation of Novel <i>N</i>-, <i>S</i>-, and <i>O</i>-Substituted 1,4-Naphthoquinone Derivatives

Abstract

Abstract Novel O- S,O- S,S- N,N- and N,S-substituted naphthoquinone compounds were prepared by reaction of 2,3-dichloro-1,4-naphthoquinone and the corresponding nucleophiles in the presence of chloroform and triethylamine or ethanol solution of Na2CO3. The structures of the novel naphthoquinone compounds were characterized by micro analysis, FT-IR, UV/Vis, 1H NMR, 13C NMR, MS, and fluorescence spectroscopy. GRAPHICAL ABSTRACT
