Abstract

A combination of tetrakis(dimethylamino)ethylene (TDAE) and palladium catalysts promoted reductive homo-coupling of aryl halides efficiently to afford the corresponding biaryls in good to quantitative yields. TDAE acted as a very mild reductant, and easily reducible functional groups, such as a nitro, formyl, ester, or nitrile group, remained unchanged.
