A New Application of Nickel Nanoparticles As AHeterogeneous Catalyst For Synthesis of 1-Amidoalkyl-2-Naphthols According To Green Chemistry Principles

1-amidoalkyl-2-naphthols were prepared via one-pot multi-component reaction of 2-naphthol, aldehydes, and amides in the presence of nickel nanoparticles as a solid phase acidic catalyst, under solvent-free condition at 100 °c. the recent literature survey reveals that the nano nickel was used as heterogeneous catalyst and received noteworthy attention because of its inexpensive, non-toxic, low corrosion, waste minimization, easy transport and disposal of the catalyst. short reaction times, high yields, and easy workup are the advantages of this protocol.
