Selenium-containing compounds have unique chemical, enzymatic and biological properties. In recent years, diselenides, as the precursors of highly reactive selenium species, have become a class of important molecules with obvious biological activities and wide chemical applications. The efficient conversion strategy of elemental selenium is an effective way for inorganic selenium to organic selenium. A general synthesis method of symmetrical diselenides from elemental selenium and aryl iodine catalyzed by nano-CuO is reported. The method is suitable for substituting products with different functional groups at ortho-, meta- and para-site. Moreover, this method has the characteristics of simple reaction method, mild reaction conditions, high yield, no production of sulfur based odor gases during the reaction process, recyclable and reusable selenium raw materials, and suitable for the preparation of hundreds of grams.

Key words: elemental selenium, nano-copper oxide, aryl iodide, selenium-containing compound, symmetrical diselenide
