## Abstract We present our results on the cyclization of (__Z__)โ€chalcogenoenynes mediated by copper(II) salts to afford 3โ€halochalcogenophenes in satisfactory yields through an intramolecular 5โ€__endoโ€dig__ cyclization. The methodology was carried out using CuCl~2~ at 50 ยฐC or CuBr~2~ at room temp
