SYNTHESIS, SPECTRAL AND ELECTROCHEMICAL PROPERTIES OF HALOGENATED 6-ALKYL-5-ARYL-1-(BENZO[<i>d</i>]THIAZOL-2-YL)-3-PHENYL- AND 5-ARYL-1-(BENZO[<i>d</i>]THIAZOL-2-YL)-3-PHENYL-6-VINYLVERDAZYLS

Abstract

A sequence of alkylation, cyclization, and oxidation reactions was used to convert 5-aryl-1-(benzo[d]thiazol-2-yl)-3-phenylformazans into 6-alkyl-5-aryl-1-(benzo[d]thiazol-2-yl)-3-phenylverdazyls and 5-aryl-1-(benzo[d]thiazol-2-yl)-3-phenyl-6-vinylverdazyls. The paramagnetic and electrochemical properties of the obtained compounds were studied.
