Chemical Generation and Reactivity of Highly Oxidized Oxo-Species of Water-Soluble μ-Carbido Ruthenium(IV) Sulfophthalocyaninate Dimer

The chemical generation of highly oxidized species of water-soluble µ-carbido ruthenium sulfophthalocyaninate dimer in the reaction with tert-butyl hydroperoxide has been studied by spectral methods. The regularities of the active species formation have been established, and a reaction mechanism has been proposed. The coordinating ability of the dimeric complex is shown to determine the possibility of formation of π-radical cation and diradical dication species. The peroxide concentration and pH of the medium have an effect on the type of generated active species capable of oxidizing not only synthetic dye, but also organic peroxide.
