A cost-effective, highly useful and eco-friendly procedure for the one-pot synthesis of highly substituted pyrazole derivatives has been developed via the reaction of various aldehydes, malononitrile and phenylhydrazine or 4-phenylthiosemicarbazide in PEG-400 and water at room temperature under ultrasound irradiation. Utilization of green solvents without a catalyst makes this methodology very interesting from economic and environmental perspectives. This method provides several advantages such as operational simplicity, use of accessible and economical starting materials and reduced environmental consequences.

Sulfonic acid-functionalized silica-coated nano-Fe3O4 particles(Fe3O4@SiO2-SO3H) have been prepared as a novel heterogeneous acid using a facile process.The material was subsequently identified as an efficient catalyst for the synthesis of a variety of tetraketone derivatives via the Knoevenagel condensation and Michael addition reactions of aromatic aldehydes to dimedone,1,3-indanedione,and 1,3-dimethyl barbituric acid.The catalyst could be readily recovered using a simple external magnet and reused several times without any significant loss in activity.The current catalytic process is both sustainable and economical because it operates under aqueous conditions,the catalyst can be recovered and reused,and the reactions themselves require only a short time and provide the products in high yield.
