Catalytic applications of {[HMIM]C(NO2)3}: As a nano ionic liquid for the synthesis of pyrazole derivatives under green conditions and a mechanistic investigation with a new approach

Catalytic applications of 1-methylimidazolium trinitromethanide {[HMIM]C(NO2)3}as the first nano ionic liquid (NIL) was studied. The described NIL was efficiently tested in the synthesis of 5-amino-pyrazole-4-carbonitrile derivatives

CuCl3: As an efficient catalyst for the preparation of 5-amino-1H-pyrazole-4-carbonitriles by anomeric based oxidation

3-Methyl-1-sulfonic acid imidazolium trichlorido copper (II) {[Msim]CuCl3} was prepared and used as a new catalyst for the preparation of 5-amino-1H-pyrazole-4-carbonitriles. In this reaction, the pyrazole ring was formed by an anomeric and vinylogous ano

Core-shell structured magnetite silica-supported hexatungstate: A novel and powerful nanocatalyst for the synthesis of biologically active pyrazole derivatives

This article describes the synthesis of a novel core-shell structured magnetic silica-supported hexatungstate (Fe3O4@SiO2-NH3[W6O19]) nanocatalyst through immobilization of hexatungstate on

Superparamagnetic Fe3O4@Alginate supported L-arginine as a powerful hybrid inorganic–organic nanocatalyst for the one-pot synthesis of pyrazole derivatives

Hybrid inorganic–organic material Fe3O4@Alg@CPTMS@Arg, was prepared by the layer-by-layer techniques through grafting l-arginine (l-arg) to Fe3O4@Alg using 3-chloropropyltrimethoxysilane (CPTMS) as a linker. Fe

Facile one-pot synthesis of 5-amino-1H-pyrazole-4-carbonitriles using alumina–silica-supported MnO2 as recyclable catalyst in water

A novel, facile, one-pot, multicomponent protocol for the synthesis of 5-amino-1H-pyrazole-4-carbonitrile derivatives has been developed using alumina–silica-supported MnO2 as recyclable catalyst in water and sodium dodecyl benzene sulphonate a

Sodium ascorbate as an expedient catalyst for green synthesis of polysubstituted 5-aminopyrazole-4-carbonitriles and 6-amino-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitriles

Sodium ascorbate (SA) was used as a safe catalyst for the synthesis of 5-aminopyrazole-4-carbonitriles from the one-pot three-component cyclocondensation (3-CC) of aldehydes, phenylhydrazine, and malononitrile at 50?°C. This 3-CC proceeds in a mixture of

Glucose-coated superparamagnetic nanoparticle-catalysed pyrazole synthesis in water

A green, benign, heterogeneous, superparamagnetic catalyst (Glu.@Fe3O4) was synthesized and characterized using Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, scanning electron microscopy and vibrating sample magnetometry. The prepared catalyst was used to achieve a high-efficiency, low-cost, eco-friendly and easy-to-handle protocol for synthesizing substituted pyrazole derivatives from aldehydes, malononitrile and phenylhydrazine. The catalyst was also used in chromene synthesis. Glucose coated on magnetic nanoparticles provided excellent catalytic activity. The catalyst could be recycled for up to four runs without significant loss in catalytic activity.

Boehmite silylpropyl amine sulfamic acid as an efficient and recyclable catalyst for the synthesis of some pyrazole derivatives

The design of biologically-active compounds is a challenging viewpoint in medicinal chemistry, and pyrazoles play a crucial role as biologically-active molecules. Methods: Up to now, a few examples have been reported for the synthesis of pyrazoles catalyz

One-pot and efficient synthesis of 5-aminopyrazole-4-carbonitriles catalyzed by potassium phthalimide

The potassium phthalimide (PPI) has been found to be an efficient, recyclable, inexpensive, commercially available, and easy to handle catalyst for the synthesis of 5-aminopyrazole-4-carbonitriles through the one-pot, three-component reaction of easily av

Novel biocompatible glucose-based deep eutectic solvent as recyclable medium and promoter for expedient multicomponent green synthesis of diverse three and four substituted pyrazole-4-carbonitrile derivatives

A novel biocompatible glucose-based deep eutectic solvent (DES) is reported for the first time in the multicomponent synthesis of diverse three and four substituted pyrazole-4-carbonitrile derivatives under catalyst-free condition without using any harmful organic solvent even for purification of the products. The desired products were obtained with high degree of diversity from the reaction of malononitrile, aromatic aldehydes and various hydrazine derivatives as nitrogen source at room temperature within short reaction times and good to excellent product yields. The deep eutectic solvent was also recycled and reused at least four times with only a slight loss of efficiency. A plausible mechanism was also proposed indicating the role of DES hydrogen bonding in the reaction promotion.
