•The gold complexes with pyridine-based selone ligands have been synthesized and characterized.•All gold complexes are efficiently catalyzed nitroarenes reduction to aromatic amines in water.
Three neutral pyridine-based selone compounds, 2,6-bis(1-methylimidazole-2-selone)pyridine (Bmsp), 2,6-bis(1-ethylimidazole-2-selone)pyridine (Besp) and 2,6-bis(1-isopropylimidazole- 2-selone)pyridine (Bpsp) have been synthesized and characterized. Reactions of HAuCl4 with pyridine-based selone ligands result in the formation of the complexes [Au(L)Cl2]+[AuCl2]− (L = Bmsp (1); L = Besp (2) and L = Bpsp (3)), respectively. All compounds have been characterized by elemental analysis, NMR IR spectra and electrospray ionization mass spectroscopic (ESI-MS). The molecular structure of 2 has been determined by X-ray crystallography. Moreover, the gold complexes are efficiently catalyzed nitroarenes reduction to aromatic amines in the presence of sodium tetrahydroborate reducing agent in water.
