Ligand Free

We have demonstrated the first ligand free CuI-nanoparticle catalyzed N-arylation of amides/cyclic amides in an ethylene glycol/2-propanol solvent system under mild conditions. This is further extended for one pot synthesis of benzimidazole, and quinazolinone via intermolecular amidation followed by cyclization.
