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 of 1 react with one proton to yield 2 and [Fe^IV(NHTs)(TAML)]⁻ (4), followed by the reaction of 4 with another proton to afford 3 and NH₂Ts.

质子促进的铁（V）-亚氨基TAML歧化成铁（V）-亚氨基TAML阳离子自由基和铁（IV）TAML。

本研究报告了非血红素铁（V）-亚氨基TAML（1）配合物质子促进歧化反应产生铁（V）-亚氨基TAML阳离子自由基（2）和铁（IV）的第一个例子）加入酸后的TAML（3）。详细的机械研究表明，两个1的分子与一个质子反应生成2和[Fe ^IV（NHTs）（TAML）] ^-（4），随后4与另一个质子反应得到3和NH ₂ Ts。
