Novel 4-(3-Bromo-2-hydroxy-5-methylphenyl)-1,3-Dithiol-2-ylidene Derivatives

Abstract

Novel 4-(3-bromo-2-hydroxy-5-methylphenyl)-1,3-dithiol-2-ylidene derivatives have been synthesized from the reaction of the corresponding 1,3-dithiol-2-ylium salts with various methylene active compounds using DBU as base. The 1,3-dithiol-2-ylium compounds have been obtained from the reaction of the substituted w-bromoacetophenone with various salts of dithiocarbamic acids. The newly obtained derivatives were characterized by NMR spectrometry, UV-Vis and IR spectroscopy.
