Herein, we report the first synthesis of chlorinated benzo[<i>b</i>]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 of diverse halogenated heterocycles, including 3-chloro, 3-bromo and 3-iodo thiophenes, selenophenes, and benzo[<i>b</i>]selenophenes was successfully accomplished under the same environmentally benign reaction conditions. This methodolo ...[more]
