Zare-Akbari, Zhila published the artcileA novel nanomagnetic solid acid catalyst for the synthesis of new functionalized bis-coumarin derivatives under microwave irradiations in green conditions, Application In Synthesis of 86-51-1, the main research area is biscoumarin preparation green chem microwave irradiation; aryl aldehyde hydroxycoumarin condensation nanomagnetic sulfosalicylic acid catalyst.
In this study, a novel, green, environmentally friendly and magnetically heterogeneous catalyst based on the immobilization of sulfosalicylic acid onto Fe3O4 nanoparticles (Fe3O4@sulfosalicylic acid MNPs) is reported. The bis-coumarin analogs I (Ar = Ph, 5-nitrothiophen-2-yl, 6-methylpyridin-2-yl, etc.) were synthesized in high yield using the reaction of 1 equiv of aryl aldehydes ArCHO with 2 equiv of 4-hydroxycoumarin in water under microwave irradiation conditions. SEM, transmission electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, thermogravimetric anal., dynamic light scattering, vibrating sample magnetometry, Fourier transform IR spectroscopy, UV-visible absorption, and Brunauer-Emmett-Teller techniques confirmed the successful synthesis of the catalyst. The main attractive characteristics of the presented green protocol are very short reaction times (10-15 min), excellent yields, and the avoidance of hazardous or toxic reagent and solvents. Thermal durability, easy separation, and high reusability are important advantages of the new catalyst in comparison to other catalysts.
