A series of bis‐[3]ferrocenophanes of the general type Fe(C5H4E’)2E−E(E'C5H4)2Fe (E=P, SiH and E’=PtBu, NneoPentyl, NSi(CH3)3) with an isolobal molecular framework have been prepared and characterized by heteronuclear NMR spectroscopy and X‐ray crystallography. The thermal dissociation behavior with respect to homolytic fission of the central bond generating phosphorus centered radicals was investigated
一系列一般类型的双-[3]二茂铁 Fe(C 5 H 4 E') 2 E−E(E'C 5 H 4 ) 2 Fe (E=P, SiH 和 E'=P t Bu,已制备出具有等瓣分子骨架的N新戊基 NSi(CH 3 ) 3 ),并通过异核核磁共振波谱和 X 射线晶体学进行了表征。使用 EPR 光谱和量子化学计算研究了中心键均裂裂变产生磷中心自由基的热解离行为。
