tors, and iv) one‐electron oxidants has been investigated (trop = 5H‐dibenzo[a,d]cyclo‐hepten‐5‐yl). 1 showed self‐re‐assembling after reactions with i) and proved surprisingly inert in reactions with ii) and iii), with the exception of CO. Reductive and oxidative cluster degradation was observed in reactions with CO and TEMPO, respectively. These reactions yielded new cluster compounds, namely a trinuclear
全铁FeN杂种[Fe 4(Ntrop)4 ](1)与i)布伦斯台德酸,ii)σ供体,iii)σ供体/π受体和iv)单电子氧化剂的反应性进行了研究(trop = 5 H-二苯并[ a,d ]环庚基-5-基)。1与i)反应后表现出自我重组装,并且在与ii)和iii)反应中表现出惰性,令人惊讶地证明是惰性的,除了CO。与CO和TEMPO反应分别观察到了还原和氧化簇降解。这些反应产生了新的簇化合物,即三核双(μ 3-imido)在前一种情况下为48个电子络合物,在后一种情况下为四核所有μ-oxo-μ-imido铁物种。表征技术包括NMR和原位红外光谱,单晶X射线分析,穆斯堡尔光谱,循环伏安法,磁化率测量和DFT计算。
