The Synthesis of Microwave Assisted Melamine-Schiff Bases and Investigation of Bridged Fe(III) Metal Complexes

Abstract

In this study, 2,4,6-triamino-s-triazine (melamine) as the starting material. Microwave assisted Schiff base reaction took place with the condensation reaction of melamine and 3-hydroxybenzaldehyde. Then, s-triazine-core Schiff base ligand complexes were obtained by obtaining a single oxygen-bridged compound of [(Fe(Salophen)Cl] ligand complexes, which we synthesized Schiff base s-triazine by literature. The obtained multidirectional s-triazine-core Schiff base ligand complexes were under microwave assisted with 3-hydroxybenzaldehyde compounds. The condensations proceed in short time to give products which, in certain instances, are not readily attainable by conventional condensation techniques. Due to its good performance, the microwave device used in household was preferred. Consequently, the structures of the obtained ligand and complexes were characterized using elemental analysis, FT-IR spectroscopy, 1H-NMR spectroscopy and magnetic susceptibility measurement techniques.
