NaHSO4–SiO2 Promoted Solvent-Free Synthesis of Triazolo [1,2-a]indazole-triones
Journal Title: International Journal of new Chemistry - Year 2014, Vol 1, Issue 3
Abstract
A new one-pot, efficient three-component condensation of dimedone, urazole and aromatic aldehydes in the presence of silica supported sodium hydrogen sulfate as an effective heterogeneous catalyst for the synthesis of novel Triazolo[1,2-a]indazole-1,3,8-trione derivatives under solvent-free conditions is described.

A theoretical study of dipole moments, energy levels and structural parameters in the Oxymetazoline drug as a nano carrier based on fullerene with changing substitution
Oxymetazoline is a decongestant. It works by constricting (shrinking) blood vessels (veins and arteries) in your body. The nasal formulation acts directly on the blood vessels in your nasal tissues. Constriction of the b...
A Comparative Study of the Carbonyl Positioning Mechanism in the Mn (CO) 5 CH2F and Mn (CO) 5CHF2 Complex through Quantum Chemistry
In this study, quantum computation was performed by density functional theory (DFT) on carbon monoxide CO placement in Mn (CO) 5CH2F and Mn (CO) 5CHF2 complexes, and all structures were geometric optimization and the CO...
Study of Nitro Factor Dislodgement in Fox-7
Since FOX-7 (1, 1-diamino-2, 2-dinitroethylene) is a relatively new energetic material, little is known about its physical and chemical properties. Therefore, first-principles quantum chemical calculations are used to pr...
