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

N-dialkyl aniline and aminonaphthalenes with phenols and naphthols using a Cr-salen catalyst under aerobic conditions was developed. Notably, air serves as an effective oxidant affording products in high selectivity. Initial mechanistic studies suggest an outer-sphere oxidation of the aniline/aminonaphthalene partner, followed by nucleophilic attack of the phenol/naphthol. Single products were observed
