Formation and dissociation kinetics of copper(II) complexes with tetraphosphorus acid DOTA analogs

Original language description

Thermodynamic and kinetic properties of Cu(II) complexes with macrocyclic cyclen-based ligands having four phosphonic acid monoester (H4dotpOEt = 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetrakis(methylphosphonic acid monoethylester)) or four phosphinic acid (H4dotpH = 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetrakis(methylphosphinic acid and H4dotpPh = 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetrakis[methyl(phenyl)phosphinic acid]) pendant arms were investigated. The formation kinetics carried out in pHrange 1-5.5 (t = 25 oC, I = 0.1 M KCl) shows that reactive species are (H2L)2MINUS SIGN and (HL)3MINUS SIGN anions and their reactivity differs by 4-5 orders of magnitude. Among studied ligands, H4dotpH is the most reactive one. Dissociation of these copper(II) complexes was investigated in the presence of perchloric acid (I = 5 M (Na,H)ClO4, proton concentration range 0.1-5.0 M) and in temperature range 10-35 oC. All studied complexes are less kinetically inert than the [Cu(dota)]2MINU
