Abstract:
In current research, we focused on the eco-friendly and efficient procedure for the synthesis of Cu(II)–proline complex functionalized with ۱,۳,۵-triazine and its grafting onto Fe۳O۴ nanoparticles [Fe۳O۴@NH۲@TCT/L-proline-Cu(II)]. The as-prepared nanocatalyst was characterized various analyses such as FT-IR, FE-SEM, TEM, BET, EDX, TGA, VSM, XRD, and ICP. In particular, the as-prepared nanocatalyst shows high activity in the one-pot syntheses of polyhydroquinoline derivatives of a wide range of aldehydes, dimedone, ethyl acetoacetate, and ammonium acetate in good to excellent yields. The experimental evidence exhibits a lot of advantages of the current procedure, such as good straightforward workup, atom-economy, and no column chromatographic separation. Also, as-prepared nanocatalyst can be retrieved from reaction media via a magnetic field, and reused over ۷ cycles without a noticeable decrease in catalytic activity.
