A simple copper salt-catalyzed synthesis of unsymmetrical diaryl selenides and tellurides from arylboronic acids with diphenyl diselenide and ditelluride

In the presence of a catalytic amount of simple copper salt, the reaction of arylboronic acids with diphenyl diselenide and ditelluride was accomplished without any additive to afford the corresponding unsymmetrical diarylselenides and tellurides in good yields.
