A recyclable functional hybrid catalyst was prepared via a simple method using chitosan as a linear polysaccharide and an ionic liquid. In this work, the synthesis of chitosan supported 1-phenyl-1H-tetrazole-5-thiol ionic liquid copper(II) complex (CS@Tet

Magnetic chitosan-copper nanocomposite: A plant assembled catalyst for the synthesis of amino- and N-sulfonyl tetrazoles in eco-friendly media

A greener, cost efficient and simple method is described to prepare copper nanoparticles (NPs) immobilized on the magnetic chitosan (one of the more versatile polysaccharides) using Euphorbia falcata leaf extract as reducing/stabilizing agent. The prepare

L -Proline: An Efficient Organocatalyst for the Synthesis of 5-Substituted 1 H -Tetrazoles via [3+2] Cycloaddition of Nitriles and Sodium Azide

A simple and efficient route for the synthesis of a series of 5-substituted 1 H -tetrazoles using l -proline as a catalyst from structurally diverse organic nitriles and sodium azide is reported. The prominent features of this environmentally benign, cost effective, and high-yielding l -proline-catalyzed protocol includes simple experimental procedure, short reaction time, simple workup, and excellent yields making it a safer and economical alternative to hazardous Lewis acid catalyzed methods. The protocol was successfully applied to a broad range of substrates, including aliphatic and aryl nitriles, organic thiocyanates, and cyanamides.

CoFe2O4 nanoparticles as a magnetically recoverable and reusable catalyst for the synthesis of arylaminotetrazoles and 5-aryloxytetrazoles

An efficient and direct method is described for the synthesis of 5-arylamino-1H-tetrazoles (Isomer A) or 1-aryl-5-amino-1Htetrazoles (Isomer B) and 5-aryloxytetrazoles from arylcyanamides or cynates with nano CoFe 2O4 as a reusable a

Application of supported Mn(iii), Fe(iii) and Co(ii) as heterogeneous, selective and highly reusable nano catalysts for synthesis of arylaminotetrazoles, and DFT studies of the products

Green synthesis of formamides using the Natrolite zeolite as a natural, efficient and recyclable catalyst

Chemoselective N-formylation of different amines was carried out with formic acid in the presence of the Natrolite zeolite as an efficient, stable and natural heterogeneous catalyst to give the corresponding formamides at room temperature under solvent-free conditions. This method has the advantages of high yields, mild conditions, simple methodology, easy work up and short reaction times. The catalyst was characterized by different techniques such as powder XRD, XRF, TGA-DTA, SEM and FT-IR spectroscopy. The Natrolite zeolite was recovered and reused several times without the significant loss of its catalytic performance.
