Carbon-supported MgO materials are excellent and sustainable catalysts for the synthesis of N-containing heterocyclic compounds by the Friedländer condensation under mild, solvent-free conditions. The results reported herein indicate that MgO is the most active catalytic species that accelerates the reaction compared with the catalytic behavior observed for the carbon material Norit RX3. On the basis of DFT calculations, a reaction mechanism that involves dual activation of the reacting structures by the catalyst is proposed. Oxide, outside: MgO supported on carbon is able to catalyze the synthesis of interesting N-containing heterocyclic compounds efficiently under mild conditions. MgO on the carbon surface is responsible for the catalytic behavior. These carbon materials are environmentally friendly catalysts for the Friedländer reaction.
