Reaction between μ-Nitridodimeric Iron(IV) Tetra-4-tert-butylphthalocyaninate and Organic Peroxides

Abstract

The reactions of μ-nitridodimeric iron(IV) tetra-4-tert-butylphthalocyaninate with tert-butylhydroperoxide and tert-butylperoxide are studied using spectroscopic methods. The kinetic parameters of the reaction are determined, and the mechanism of the process is suggested. Activation of organic peroxide is preceded by its coordination with the dimeric iron complex. The coordinated and activated substrate oxidizes μ-nitridodimeric iron(IV) tetra-4-tert-butylphthalocyaninate at the macrocycle to yield the radical cation form. The oxidized species can be easily reduced to the neutral species in the presence of a nitrogen-containing base.
