Symmetrical diaryl selenides were synthesized in moderate-to-excellent yields by Cu-catalyzed C(aryl)Se bond formation followed by the reaction of triarylbismuthanes with elemental Se in the presence of Cu(OAc)2 and 1,10-phenanthroline (10 mol%) under aerobic conditions. This reaction proceeded efficiently: All the aryl groups on Bi were transferred to the coupling products.

Tributyltin aryl selenides are highly efficient arylselenating agents in reactions with aryl iodides and aryl triflates under catalysis with Pd and Ni complexes respectively. They also may be used as efficient source of active arylselenolate anion in the presence of fluoride ions in reaction of arylselenation of alkyl halides and activated aryl fluorides.
