Opis

A green chemistry approach for organic synthesis is described here, which involves microwave exposure of reactants in presence or absence of solvents. A novel and simple method has been developed for the synthesis of triazole derivatives under microwave irradiation. A new series of Nano complexes of 2-(1,2,4-triazol-3-ylimino)methyl)-6-methoxyphenol under microwave irradiation. The microwave methodology is rapid and gives a better yield (80-98%). The prepared Schiff base was used for further complex formation reaction with different metal ions using Mn(II), Co(II), Ni(II) and Cu(II) complexes by with a molar ratio of ligand: metal as 1:1. The stereochemistry and the mode of bonding of the complexes were achieved based on elemental analysis, FTIR, UV-Vis, 1HNMR, 13CNMR and Mass Spectroscopy as well as Thermo-Gravimetric Analysis (TGA). Structures proposed for geometry of the chelates based on their electronic spectra and magnetic susceptibility. The solid complexes have been synthesized and studied by TGA analysis. The thermal dehydration and decomposition of the complex was studied kinetically using the integral method applying the Coats-Redfern and Horowitz Metzger equation.
