Abstract: Mononuclear nonheme iron(V)-oxo complexes have been reported previously. Herein, we report the first example of a mononuclear nonheme iron(V)-imido complex bearing a tetraamido macrocyclic ligand (TAML), [(TAML)Fe-V(NTs)](-) (1). The spectroscopic characterization of 1 revealed an S = 1/2 Fe(V) oxidation state, an Fe-N bond length of 1.65(4) angstrom, and an Fe-N vibration at 817 cm(-1). The reactivity of 1 was demonstrated in C-H bond functionalization and nitrene transfer reactions.
