Iron-catalyzed regioselective direct oxidative aryl-aryl cross-coupling

Article abstract of DOI:10.1021/jo202152b

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).
