Synthesis, spectroscopic characterization and catalytic activity of UO2 with a tridentate Schiff base ligand

Schiff base and related complexes cover a wide range of application in catalytic fields and they are great research interest. Due to the formation of stable complexes with transition metal ions and participation of azomethine linkage in the chelation process, Schiff bases are considered as a model compound and play active role in the development of coordination chemistry [1]. Schiff base complexes possess high stability in different oxidation states resulting in a wide range of application for these complexes, such as bio catalytic [2] and catalytic activities [3]. A tridentate Schiff base ligand, (E)-2-(((2-aminophenyl)imino)methyl)-6-methoxyphenol (H2L), and its uranyl(VI) complex [UO2(L)(PrOH)], have been synthesized and characterized using physicochemical and spectroscopic methods such as molar conductivity, elemental analysis, 1HNMR, UV-Vis and FT-IR. The prepared compound was also screened for catalytic activities. The catalytic activities were investigated on the multicomponent reactions of malononitrile and aromatic aldehydes.
