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 HgII in good to high yields.
