▎ 摘　　要

We present a novel pincer ligand based on the pyridine scaffold for functionalizing magnetic GO (graphene oxide). Pincer ligands are known for their great control of coordination spheres in catalysts. GO is used as solid support for immobilizing gold nanoparticles to synthesize a heterogeneous catalyst for reducing nitroarenes. The reduction of nitroarenes to aromatic amines is not only of environmental importance but can be used as a model reaction too. The yields of the reduction reactions are promising. Additionally, the reaction conditions are mild and the catalyst has good recyclability and great stability. The nanocatalyst was monitored and characterized by spectroscopic methods.
