Synthesis,Characterization and Oxygenation Property of Bisbenzoin-semitriethylenetetraamine and Its Bisnucleus Transition Metal Complexes

Abstract

Abstract: Bis-benzoin-semitriethylenetetraamine was synthesized in yield 89% via the reaction of benzoin with triethylenetetraamine by refluxing in ethanol(95%), and complexes of Co(Ⅱ), Cu(Ⅱ), Ni(Ⅱ), Zn(Ⅱ) and Cd(Ⅱ), coordinated by it and oxalic acid were also synthesized by metal salts, bis-benzoin semitriethylenetetraamine and H₂C₂O₄ in CH₂Cl₂ solvent. They were all characterized by elementary analysis, IR, MS, molar conductivity and thermal analysis. The saturated oxygen uptake of the complexes in DMFsolvent at 0 ℃ obtained by manometric uptake measurements is two mmol O₂ per mmol complex.

Key words: Bis-benzoin-semitriethylenetetraamine, Synthesis, Oxygenation property, Transition metal
