In the present study, a mol. level engineered-based method was used to synthesize a copper-based nanomagnetic catalyst (Fe3O4@CQD@Si(OEt)(CH2)3NH@CC@N3@phenylacetylene@Cu). The as-synthesized catalyst was characterized using different techniques, including IR, X-ray powder diffraction (XRD), field emission SEM (FESEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), EDX elemental mapping, induced coupled plasma (ICP), thermal gravimetric anal. (TGA), DTA, and a vibrating sample magnetometer (VSM). The Fe3O4 nanoparticles surface was protected using carbon quantum dots (CQDs) instead of conventional SiO2. The activity of the as-synthesized catalyst was evaluated in the synthesis of 1-aminoalkyl-2-naphthols derivatives, e.g., I. The solvent-free condition has short reaction time and high reaction yield, 87.5% after five cycles. How the reaction was triggered by the catalyst was determined by IR. Strong evidence was provided for the stability of the as-synthesized novel copper-based heterogeneous magnetic nanocatalyst. The effect of temperature and the amount of the catalyst (optimal reaction conditions) were determined using a systematic approach, namely, the design of experiment (DOE). The results came from multiple reactions, including the reaction of 3-Hydroxybenzaldehyde(cas: 100-83-4Application In Synthesis of 3-Hydroxybenzaldehyde)
3-Hydroxybenzaldehyde(cas: 100-83-4) can be used as a reactant along with ethyl acetoacetate and thiourea in the synthesis of corresponding dihydropyrimidine-2-thione (monastrol), using Yb(OTf)3 as a catalyst by Biginelli cyclocondensation reaction.Application In Synthesis of 3-Hydroxybenzaldehyde
