An eco-safe and facile multi-component domino reaction has been described for the synthesis of 1H-pyrazolo [1, 2-b] phthalazine-5, 10-dione derivatives. The products were obtained by a four-component condensation reaction between phthalimide, hydrazine monohydrate, aromatic aldehyde derivatives and malononitrile in the presence of a catalytic amount of copper (II) oxide (CuO) ...

Catalytic activity of AlHMS was investigated as a cheap heterogeneous reusable catalyst in some multi-component reactions for the synthesis of various chromenes. Three-component reaction of 2-hydroxy-naphtoquinone with an aromatic aldehyde and dimedone or barbituric acid in H2O under reflux conditions was performed using AlHMS in relatively good yields. The approach was more extended using psue...

nano tin dioxide was employed as a catalyst for efficient and facile preparation of pyran derivatives via the one-pot three component condensation reaction of various aldehydes with malononitrile and dimedone. chromene derivatives via the one-pot three component condensation reaction of various aldehyde with malononitrile and 4-hydroxycoumarin were also synthesized by this novel catalyst. the d...

Multi-component coupling reaction (MCR) is a powerful synthetic tool for the synthesis of biologically active compounds. Development of such multi-component coupling reaction strategies in visible light has been of considerable interest, as they provide simple and rapid access to a large number of organic molecules through a sustainable path. An efficient and green protocol for the synthesis of...

This paper outlines the synthesis of CuFe2O4 nanoparticles and their catalytic applications. CuFe2O4 nanoparticles were synthesized via microwave-assisted co-precipitation method. The obtained nanoparticles characterized through Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. Vibrating sample magnetometer shows nanoparticles exhibit ferromagnetic be...
