New Heterocyclic Compounds From Butadienyl Sulfanes and Thiols

Abstract

2-Chloroethyl-pentachlorobutadienyl-sulphide reacts with some heterocyclic thiols(7-mercapto-4-methylcoumarin,2-mercaptobenzimidazole derivatives etc.) in water-ethanol mixture in the presence of sodium hydroxide to give the new heterocyclic thioethers. New 2-(4-(2chloro-ethylthio)-1,2,3,4-tetrachlorobuta-1,3-dienylthio)ethanol compound was obtained from the reaction of 1,4-bis(2-hydroxyethylthio)1,2,3,4-tetrachloro-1,3-butadiene with SOCl2 in pyridine. The structures of the new compounds were characterized by elemental analysis, FT-IR, H-1 NMR, C-13 NMR, MS and fluorescence spectrophotometry.
