versus Fc+/Fc in the coordinating solvent MeCN (E °′=1.21 V), but also in almost non‐coordinating o DFB (=1,2‐F2C6H4; E °′=1.29 V). It allows for the deelectronation of [FeIIICp*2]+ to [FeIV(CO)Cp*2]2+ and [FeIV(CN‐t Bu)Cp*2]2+ in common laboratory solvents and is compatible with good σ‐donor ligands, such as L=trispyrazolylmethane, to generate novel [M(L)x ]n + complex salts from the respective elemental
全氟化二氢吩嗪衍生物(全氟-5,10-双(全氟苯基)-5,10-二氢吩嗪)(“吩嗪F ”)可以通过Ag [Al]的脱电(即氧化)容易地转化为稳定且可称量的自由基阳离子盐。 (OR F)4 ] / Br 2混合物(R F= C(CF 3)3)。作为无毒的去电子剂,与配位溶剂MeCN(E °′= 1.21 V)中的Fc + / Fc相比,它具有强大且完全可逆的半波电势,但在几乎不配位的o DFB(= 1,2-F)中,2 C 6 H 4 ; E°′= 1.29 V)。它允许在普通实验室溶剂中将[Fe III Cp * 2 ] +脱电子为[Fe IV(CO)Cp * 2 ] 2+和[Fe IV(CN- t Bu)Cp * 2 ] 2+。具有良好的σ供体配体(例如L =三吡唑基甲烷),可以从相应的元素金属中生成新颖的[M(L)x ] n +络合盐。
