Preparation new ligands containing nitrogen and spectrophotometric study with Rhenium complexes.
Abstract
The preparation of two new ligands containing nitrogen atoms as chelates from Mannich reaction was described in this work. Using formyl aminophenols as the compound containing the active proton center, glycine as the amine, and paraformaldehyde as the aldehyde performed the reaction. The method was successful and was very promising to design ligand of various molecular structures. These ligands were capable to coordinate to rhenium metal by ligands exchange methods.
These compounds were studied spectrophotometrically,so as their complexes with rhenium by using infrared and U.V-vis absorption spectroscopy,as well as the other classical techniques such as microanalysis and molecular weight determination by depression of freezing point. The following chemical structure for preparation ligands.
