σ-Hydrocarbyl complexes of the form [M(η-PCMe)(μ-η:η-CHPh)K(η-arene)] (M = La, Ce, Pr, U, Np, Pu; arene = benzene or toluene) were synthesised in one-pot reactions from [MI(THF)], or [U(BH)(toluene)] (M = U). All complexes were examined by multinuclear (H, C{H}, P{H}) NMR and UV-vis-NIR spectroscopy, as well as single-crystal X-ray diffraction from which molecular metal-phosphorus bonds for Np and Pu, and a σ-hydrocarbyl metal-carbon bond for Pu, have been structurally authenticated.
通过一锅法反应，由[MI(THF)]或[U(BH)(甲苯)]（M = U）合成了[M(η-PCMe)(μ-η:η-CHPh)K(η-芳烃)]形式的σ-烃基配合物（M = La、Ce、Pr、U、Np、Pu；芳烃 = 苯或甲苯）。通过多核（H、C{H}、P{H}）核磁共振和紫外可见近红外光谱对所有配合物进行了研究，还通过单晶X射线衍射进行了研究，从中已对Np和Pu的分子金属-磷键以及Pu的σ-烃基金属-碳键进行了结构鉴定。
