Oxidative dimerization of 1,3-dienes on Ni(0) is one of the most fundamental elemental processes; however, the molecular structure of the key intermediate, Ni(C₈H₁₂)(L), arising from 1,3-butadiene had not yet been defined. We first identified the detailed structure of Ni(C₈H₁₂)(L) (L = PCy₃) by X-ray crystallography and revealed that the C8 moiety was bound to Ni in an η¹:η³ fashion with a cis-C–C double bond of the σ-allyl group located in the same face with the central carbon of the π-allyl group. In addition, the formation of the corresponding anionic complexes upon treatment with organometallic reagents was confirmed by NMR.

Ni（C8H12）（L）配合物的结构及其对有机金属试剂的反应性

Ni（0）上的1,3-二烯氧化二聚是最基本的元素过程之一；然而，尚未确定由1,3-丁二烯产生的关键中间体Ni（C ₈ H ₁₂）（L）的分子结构。我们首先确定的Ni（C的详细结构₈ ħ ₁₂）（L）（L = PCY ₃通过X射线晶体学），并发现该C8部分结合至Ni中的η ¹：η ³方式与顺式- σ-烯丙基的cc双键与π-烯丙基的中心碳位于同一面上。另外，通过NMR证实了在用有机金属试剂处理后形成相应的阴离子配合物。
