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(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) Å, and an Fe-N vibration at 817 cm. The reactivity of 1 was demonstrated in C-H bond functionalization and nitrene transfer reactions.

单核非血红素铁（V）-氧络合物以前已有报道。在此，我们报告首例单核非血红素铁（V）-亚胺配合物，其具有四氨大环配体（TAML）[(TAML)Fe(NTs)]（1）。1 的光谱特性表明其具有 S = 1/2 的 Fe(V)氧化态，Fe-N 键长为 1.65(4) Å，Fe-N 振动频率为 817 cm。1 的反应活性在 C-H 键功能化和氮烯转移反应中得到了证明。
