Dissociation kinetics study of copper(II) complexes of DO3A, DOTA and its monosubstituted derivatives
Original language description
The kinetic inertness of copper(II) complexes with cyclen-based ligands having three (H3do3a) or four (H4dota) acetic acid arms and those with 3 acetic acid and one phosphonic (H5do3ap), phosphinic (H5do3ap(PrA) , H4do3ap(ABn)) acid or methylpyridine-N-oxide (H3do3a-pyNox) pendant arms has been studied. The proton-assisted decomplexation reaction was studied under a wide range of conditions to fully assess the parameters influencing the reaction (temperature range 25-60 oC, proton concentration range 0.05-5 M and presence of perchlorate or nitrate anions). The empirical rate law k(d,obs) = k(0) + k(H) x [H+], involving solvolytic and proton-assisted dissociation pathways, shows that the complexes can be divided into two groups according to their kinetic behavior. Complexes of ligands having only carboxylate pendant arms (H3do3a, H4dota) show higher kinetic inertness than those of ligands with mixed pendant arms (H5do3ap, H5do3ap(PrA), H4do3ap(ABn), H3do3a-pyNox).
