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...
First Princiles Study of the Electron Transport Properties of Buthane-dithiol Nano-Molecular Wire
We report a first-principles study of electrical transport in a single molecular conductor consisting of a buthane-dithiol sandwiched between two Au (100) electrodes. We show that the current was increased by increasing...
