Magnetically recoverable copper ferrite catalyzed cascade synthesis of 4-Aryl-1H-1,2,3-triazoles under microwave irradiation

Magnetically active CuFe2O4 catalyzed cascade synthesis of 4-Aryl-1H-1,2,3-triazoles under microwave irradiation starting from aromatic aldehydes, sodium azide and nitromethane has been developed and demonstrated here. The catalyst system needed for the purpose was prepared following a procedure by A. Dandiya et al. with a slight modification and was characterized using FT-IR, XRD, SEM-EDX and TEM analysis. The most notable advantage of the developed methodology is the excellent time economy to carry out the transformation. Other features include simple operating procedure, wide substrate coverage and easy recovery of the catalyst. Reusability of the catalyst has been tested and found to be very satisfactory up to sixth cycle without significant loss in efficiency. All the synthesized compounds have been characterized using FTIR, 1H & 13CNMR spectroscopy, HRMS.

Selective gas adsorption in the flexible metal-organic frameworks Cu(BDTri)L (L = DMF, DEF)

Use of the ditopic ligand 1,4benzenedi(1H-1,2,3-triazole) (H 2BDTri) enabled isolation of two new three-dimensional metal-organic frameworks of formulae Cu(BDTri)L in which L = DMF (1) and diethylformamide (DEF; 2). These compounds have the same primary structure, featuring one-dimensional channels with the bridging DMF or DEF molecules pointing into the cavity. Upon exposure to solvent vapors, both display a reversible flexibility, as characterized by single-crystal to single-crystal phase transitions in 1. The O2 adsorption isotherms for the compounds show a twostep adsorption behavior associated with a permanent microporosity and a pore-opening process. In the case of N2 adsorption, only 1 exhibits a two-step adsorption isotherm, whereas 2 does not present any pore opening, demonstrating that design of a flexible framework cavity can control the pore opening and thereby possibly enhance O2/ N2 separation.

Facile Synthesis of 1,3,5-Triarylbenzenes and 4-Aryl-NH-1,2,3-Triazoles Using Mesoporous Pd-MCM-41 as Reusable Catalyst

We report mesoporous nano-Pd-MCM-41 catalyzed rapid and efficient synthesis of 1,3,5-triarylbenzenes via de-nitrative cyclotrimerization of β-nitrostyrenes. All the reactions were very fast and high yielding. The Pd-MCM-41 was also very effective in catalyzing de-nitrative [3+2] cycloaddition of β-nitrostyrenes with TMSN3 to synthesize 4-aryl-NH-1,2,3-triazoles. The catalyst was reused at least up to eight times with minimum loss of catalytic activity.

On Water Cu@g-C3N4 Catalyzed Synthesis of NH-1,2,3-Triazoles via [2+3] Cycloadditions of Nitroolefins/Alkynes and Sodium Azide

Here, we have reported fabrication of graphitic polymeric C3N4 supported CuCl2 (Cu@g-C3N4) and characterized by powder X-ray diffraction, field emission scanning electron microscopy, high resolution transmission electron microscopy, X-ray photoelectron spectroscopy studies. An efficient and regioselective protocol for the on water synthesis of 4-aryl-NH-1,2,3-triazole derivatives via 1,3-diipolar cycloaddition reactions of nitroolefins/phenylacetylenes to sodium azide were demonstrated by using Cu@g-C3N4 as robust and reusable catalyst.
