Copper nanoparticle decorated organically modified montmorillonite (OMMT): An efficient catalyst for the N-arylation of indoles and similar heterocycles

A highly active ligand-free and efficient copper nanoparticle decorated OMMT catalyzed N-arylation of NH-heterocycles, i.e. indole, imidaole, benzimidazole, pyrrole, carbazole has been demonstrated. (C) 2014 Elsevier B.V. All rights reserved.
