Herein, we report an efficient method for the synthesis of alkynyl selenides and tellurides from terminal alkynes and diorganyl diselenides or ditellurides using CuO nanopowder as a recyclable catalyst. This new methodology furnished the desired products in good to excellent yields. Furthermore, the catalyst was easily recovered and reused for further catalytic reactions without loss of activity.
