The article conveys some information:
In this work, the new trinuclear manganese catalyst defined as Fe3O4@NFC@NNSM-Mn(III) was successfully manufactured and fully characterized by different techniques, including FT-IR, XRD, TEM, SEM, EDX, VSM, and ICP anal. This magnetic catalysts used for the synthesis of xanthene derivatives I [R = Ph, 4-ClC6H4, 1H-indol-3-yl, etc.; R1 = H, Me]. The critical potential interest in the present method included short reaction time, high yields, recyclability of the catalyst, easy workup and ability to sustain a variety of functional groups, which gave economical as well as ecol. rewards. Also, the synthesized catalyst was used as a recyclable trinuclear catalyst for synthesis of carbonyl compounds via alc. oxidation reactions at 40°C. The magnetic catalyst activity of Fe3O4@NFC@NNSM-Mn(III) could be attributed to the synergistic effects of the catalyst Fe3O4@NFC@NNS-Mn(III) with melamine. Employing a sustainable and safe low temperature, using an eco-friendly solvent, no need to use any additive, and long-term stability and magnetic recyclability of the catalyst for at least six successive runs were the advantages of current protocol toward green chem. This protocol was a benign, environmentally friendly method for heterocycle synthesis. The experimental part of the paper was very detailed, including the reaction process of (4-Bromophenyl)methanol(cas: 873-75-6Related Products of 873-75-6)
