Abstract
This research focuses on developing a novel acidic nano-catalyst by sulfonating magnetic graphene oxide coated with 5-amino-1H-tetrazole (GO/Fe3O4@CPTMS@5-amino-1H-tetrazole @SO3H). Various techniques, such as FTIR, EDX, mapping, FESEM, XRD and VSM analyses, were employed to investigate and confirm the properties of the synthesized nanocomposite. It demonstrated exceptional performance in the green synthesis of 4,4′-(arylmethylene)bis-(3-methyl-1-phenyl-1H-pyrazol-5-ol) derivatives. Key benefits of this process include its environmentally friendly catalyst, solvent-free conditions, straightforward purification, cost-efficiency, high product yield, short reaction time, and low reaction temperature. Furthermore, the magnetic catalyst exhibited excellent stability and reusability over four consecutive cycles, aligning with green chemistry principles.
期刊介绍：
Launched in January 1998, Inorganic Chemistry Communications is an international journal dedicated to the rapid publication of short communications in the major areas of inorganic, organometallic and supramolecular chemistry. Topics include synthetic and reaction chemistry, kinetics and mechanisms of reactions, bioinorganic chemistry, photochemistry and the use of metal and organometallic compounds in stoichiometric and catalytic synthesis or organic compounds.
