Electrode material promoted dehydrogenative homo-/cross-coupling of weakly activated naphthalenes
Abstract
Herein, we reported an electrochemical dehydrogenative homo-/cross-coupling of weakly activated naphthalene in the exogenous transition metal- and oxidants-free manner. Benefiting from the microscopic interaction between the reactants and the carbon plate anode, the electropolymerization of aromatic rings was suppressed. And a series of binaphthyl and naphthalene-aryl privileged scaffolds were obtained in 28%–90% yields by homo- or cross-coupling. This C(sp2)-H activation strategy featured atom and step economy as well as the ready scalability.
