A simple, environmentally friendly and economical route for the preparation of a novel copper-Schiff-base organometallic complex on Fe3O4 nanoparticles (Fe3O4@Schiff-base-Cu) using an inexpensive and simple method and available materials is presented. This magnetic nanocatalyst was comprehensively characterized using Fourier transform IR spectroscopy (FT-IR), X-Ray Diffractometer (XRD), inductively coupled plasma at. emission spectroscopy (ICP), energy-dispersive X-ray spectroscopy (EDS), SEM (SEM), X-ray mapping, thermogravimetric anal. (TGA) and vibrating sample magnetometer (VSM) anal. In the second stage, the catalytic activity of this catalyst was studied in the synthesis of polyhydroquinoline derivatives I [R = Ph, 4-ClC6H4, 3,4-(HO)2C6H3, etc.] via Hantzsch reaction of aryl aldehydes RCHO, dimedone, Et acetoacetate and ammonium acetate in water as a green solvent. A simple preparation of the catalyst from the com. available materials, high catalytic activity, simple operation, short reaction times, high yields and use of green solvent can be regarded as advantages of this protocol. In addition, this nanocatalyst was easily recovered using external magnet and reused for several times without significant loss of its catalytic efficiency. Finally, the leaching, heterogeneity and stability of Fe3O4@Schiff-base-Cu were studied by hot filtration test and ICP technique. In addition to this study using 3-Hydroxybenzaldehyde, there are many other studies that have used 3-Hydroxybenzaldehyde(cas: 100-83-4HPLC of Formula: 100-83-4) was used in this study.
3-Hydroxybenzaldehyde(cas: 100-83-4) is used as an ionophore, during the development of an highly selective and sensitive PVC membrane sensor, which can be used as a Tb3+ ion selective electrode.HPLC of Formula: 100-83-4
