二苯基二硒醚在DMSO中于室温下，在催化量的碘化铜存在下，与末端的炔烃反应，得到好的或极好的炔基苯基硒的产率。该反应在中性条件下进行，溶剂作为氧化剂。二苯二硫醚和二硫化二碲发生类似的反应，但需要弱无机碱的存在。(C)2004年，爱思唯尔有限公司出版。
Diphenyl diselenide reacts with terminal alkynes at room temperature in DMSO in the presence of catalytic amounts of copper iodide to give good to excellent yields of alkynyl phenyl selenides. The reaction occurs under neutral conditions and the solvent acts as the oxidant. Diphenyl disulfide and ditelluride undergo the analogous reaction, but require the presence of a weak inorganic base.
