Proton-promoted disproportionation of iron(v)-imido TAML to iron(v)-imido TAML cation radical and iron(iv) TAML

摘要

The present study reports the first example of a proton-promoted disproportionation reaction of a non-heme iron(v)-imido TAML (1) complex to give an iron(v)-imido TAML cation radical (2) and an iron(iv) TAML (3) upon addition of acids. Detailed mechanistic investigations revealed that two molecules of1react with one proton to yield2and Fe-IV(NHTs)(TAML)(-)(4), followed by the reaction of4with another proton to afford3and NH2Ts.
