Ligand interactions substitution

Metal-ligand interactions can be used to construct structurally well-defined assemblies of Pcs. In this context, a well-established method in the field of porphyrin chemistry, developed by Kobuke and coworkers, is the preparation of imidazolyl-substituted porphyrins which can coordinate through the imidazolyl group to the... [Pg.18]

Ligand-substitution reactions in aqueous solutions rarely proceed directly. Instead, the leaving ligand is first replaced by H2O, which is present in aqueous solution at a concentration of 55 M, the entering ligand then substitutes the metal-bound H2O (M-OH2) inthe so-called anationreaction. Therefore, the rate constant of forward reactions, which could be considered as the reactivity of aquo-metal species, will parallel the order of water substitution in the inner coordination sphere of the corresponding metal ions Cs > Ba > Hg2+ > K+ > Cr2+ Cu + > Na+ > Sr + Li+ > Ca + > Cd + > Mn2+ Zn + > Fe + > Co + > Mg + > nP+ > Pd + > Pt + > cases, the interactions between... [Pg.3170]
