Synthesis and characterization of hierarchical ZSM-5 zeolite containing Ni nanoparticles for one-pot reductive amination of aldehydes with nitroarenes

In this paper, we wish to report the synthesis and characterization of nickel nanoparticles supported on acidic form of ZSM-5 zeolite (Ni/H-mZSM-5) with microporous/mesoporous hierarchical structure. This catalyst was effectively employed as novel acid-metal hi-functional heterogeneous catalyst for direct one-pot reductive amination of aldehydes with nitroarenes in the presence of NaBH4 as a mild reducing agent. Excellent yields at room temperature and short reaction time in aqueous media conditions were obtained. (C) 2015 Elsevier B.V. All rights reserved.
