已知化合物[Cp‡Fe(CO)2]2和新的更易溶的化合物[Cp†Fe（CO)2]2 （Cp‡= η5-C5Ph5; Cp†= η5-C5Ph4（对甲基）））是通过一种新的非常有效的途径制备的，该途径是通过三烷基自由基从Cp‡Fe(CO)2H和Cp†Fe(CO)2H氢化物中提取氢原子。二聚体热解离成相应的17电子单体，Cp‡Fe(CO)2和Cp†Fe(CO)2，它们可能呈“平面”（C2v）结构，OC - Fe - CO键角为~ 90°。
The known compound [Cp‡Fe(CO)2]2 and the new, more soluble [Cp†Fe(CO)2]2 (Cp‡ = η5-C5Ph5; Cp† = η5-C5Ph4(p-tolyl)) are prepared via a new, very effective route involving hydridic hydrogen atom abstraction from the hydrides, Cp‡Fe(CO)2H and Cp†Fe(CO)2H, by the trityl radical. The dimers dissociate thermally to the corresponding 17-electron monomers, Cp‡Fe(CO)2 and Cp†Fe(CO)2, which probably assume “planar” (C2v) structures with OC−Fe−CO bond angles of ∼90°.
