Abstract
Cofacial Fe2, Co2, and Ni2 complexes supported by a para-terphenyl diphosphine ligand were prepared. Central arene deplanarization and a μ2:(η(3),η(3)) coordination mode suggest partial bisallyl character in the Fe2 and Co2 complexes. An oxidation induced shift in Fe2-arene binding highlights the non-innocent nature of the arene ligand.
摘要
制备了由对三联苯二膦配体支持的共面 Fe2、Co2 和 Ni2 配合物。中心芳环去平面化和 μ2:(η(3),η(3)) 配位模式表明 Fe2 和 Co2 配合物中存在部分双烯丙基特征。Fe2-芳环键合的氧化诱导位移突出了芳环配体的非固有性质。
