Redox-controlled selectivity of C-H activation in the oxidative cross-coupling of arenes
Gold brings us together: Taking advantage of the orthogonal reactivities of AuI and AuIII towards C-H activation of electron-poor and electron-rich arenes, respectively, a novel approach for the synthesis of biaryls through double C-H activation is proposed. Stoichiometric studies demonstrate that these oxidative couplings occur with high selectivity at low temperature. Copyright
