Homocoupling of Substituted Benzenes to Symmetrical Biaryls with Mercury(II) in the Presence of Cerium(IV)

Abstract

Homocoupling of substituted benzenes to symmetrical biaryls is achieved with different cerium(IV) compounds such as cerium(IV) triethylammonium nitrate (CTEAN), cerium(IV) pyridinium nitrate (CPN) and Ce(OTf)₄ in the presence of Hg^II in good to high yields.
