Kinetic study works well. Ligand synthesis can be improved.


This paper reports an interesting property of the O, N and S donor ligand 2-(2’-Hydroxy-3’-methoxyphenyl)benzothiazole which makes it switch chelating donor sites from O, S (at pH < 5.0) to O, N (above pH 5.0) while reacting with Cu(II) acetate in a 3:1...
