Regioselective iron-catalyzed cross-dehydrogenative coupling (CDC) of two aromatic compounds using tert-BuOOH as oxidant under mild conditions has been reported. The direct oxidative coupling reaction is selective toward creation of a carbon-carbon bond at the position ortho to the functional groups of the substrates, completely preventing the homocoupled products. The C-C bond-forming reaction makes the method versatile, leading to functionalized 2,2′-disubstituted biaryls (Figure presented).

Cerium (IV)-mediated intermolecular direct biaryl coupling of aromatic tertiary amines and naphthol via dual CH bond activation has been reported. The new CC bond is formed regioselectively ortho to the amino and hydroxyl substituents under oxidative conditions to give substituted bifunctional amino naphthols. We report here the use of Ce-MCM-41 catalyst for the synthesis of these unsymmetrical biaryls via oxidative cross coupling under mild conditions. The catalyst was recovered by simple filtration and reused for several cycles with consistent activity.
