title: An efficient one-pot synthesis of symmetrical diselenides or ditellurides from halides with CuO nanopowder/Se0 or Te0/base.
abstract: A CuO nanopowder-catalyzed coupling reaction of aryl, alkyl, and heteroaryl iodides with elemental selenium and tellurium takes place in the presence of KOH at 90 degrees C in DMSO. A wide range of substituted symmetrical diselenides and ditellurides were afforded with good to excellent yields.
