Green synthesis of halogenated thiophenes, selenophenes and benzo[b]selenophenes using sodium halides as a source of electrophilic halogens

Herein, we report the first synthesis of chlorinated benzo[b]selenophenes via environmentally friendly electrophilic chlorocyclization reaction using “table salt” as a source of “electrophilic chlorine” and ethanol as a solvent. In addition, the synthesis

Copper(II)-mediated intramolecular cyclization of (Z)-chalcogenoenynes: Synthesis of 3-halochalcogenophene derivatives

We present our results on the cyclization of (Z)-chalcogenoenynes mediated by copper(II) salts to afford 3-halochalcogenophenes in satisfactory yields through an intramolecular 5-endo-dig cyclization. The methodology was carried out using CuCl2
