A green method for the preparation of triazoloindazoles by multicomponent reaction of dimedone, benzaldehydes, and phenylurazole using fibrous nanosilica (KCC-1) as catalyst is developed. [ABSTRACT FROM AUTHOR]

The new eco-friendly catalyst can be easily recovered by filtration and reused for several times without significant loss of activity. [ABSTRACT FROM AUTHOR]

The fibrous nano-silica supported heteropolyacid-based ionic liquid is simply and cost-effectively synthesized and exhibits high catalytic activity in the synthesis of cyclic carbonates (III) under mild and solvent-free conditions. [ABSTRACT FROM AUTHOR]

A novel heterogenized gold(III) catalyst is synthesized and used for the synthesis of dihydroisoindoles in water. [ABSTRACT FROM AUTHOR]

The preparation of new salen complex-functionalized Fe3O4/SiO2 magnetic nanoparticles is described. [ABSTRACT FROM AUTHOR]

An abstract of the article "Quinuclidine Stabilized on FeNi3 Nanoparticles as Catalysts for Efficient, Green, and One-Pot Synthesis of Triazolo[1,2-a]indazole-triones," by S. M. Sadeghzadeh is presented.

A newly synthesized catalyst effectively catalyzes the formation of benzopyran derivatives (IV) and (VI). [ABSTRACT FROM AUTHOR]
