spectroscopic studies. Molecular structures of complexes 1, 2 and 4 were determined by X-ray crystallography. Copper complexes (1-4) were employed as a catalyst for the [3+2] cycloaddition and A3-couplingreactions. A mutual approach of salen-type ligands and metal via active participation of ligands allow to achieve the catalytic reactions. Reaction pathways were proposed and possible intermediate species
Nano magnetite supported metal ions as robust, efficient and recyclable catalysts for green synthesis of propargylamines and 1,4-disubstituted 1,2,3-triazoles in water
Nano magnetite functionalized 2,2′-biimidazole complex of metal ions Cu(I), Cu(II), Ni(II) and Co(II) were successfully synthesized and characterized by different techniques such as elemental analysis, FT-IR spectroscopy, X-ray diffraction (XRD), thermo gravimetric analysis (TGA), transmission electron microscopy (TEM), scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM with

bifunctional silica‐based solid catalyst that possessed an ionicliquid tail and a metal acetylacetonate moiety was prepared through a mild Lewis‐acid‐catalyzed ring‐opening reaction with a thiol‐functionalized silica. The surfactant‐combined silica‐supported metal acetylacetone catalysts displayed excellent catalytic activity in water for a range of reactions. The solid catalyst was also shown to be recyclable
