Synthesis and characterization of 1,2,3-selena/thiadiazoles linked to other heterocyclic units

Abstract

Synthesis of novel 1,2,3-selena/thiadiazoles, linked to different benzo-1,3-heteroazole ring by sulfur has been reported. Structural features of the compounds have been analyzed by ¹H and ¹³C NMR, mass and single crystal X-ray studies.

Keywords:

• Oxidation
• Selenium heterocycles
• Sulfur heterocycles
• Phase transfer catalysis
• X-ray diffraction
