A rational synthetic pathway towards a series of -P-bearing multi-decker complexes was developed. The combination of [CpFe(μ,η-P)] (A) with low-valent transition metal cations yields a series of triple-decker complexes [CpFe(μ,η-P)MCp'''][WCA] (M = Cr - Ni; WCA = weakly coordinating anion, Cp''' = 1,2,4-BuCH). Utilizing the arene complexes [M(CR)][WCA] (M = Fe, Co) instead allowed the synthesis of the unprecedented -P-containing quadruple-decker complexes [{Cp*Fe(μ,η-P)}M][] (M = Fe, Co).
开发了一条通向一系列含磷多夹层配合物的合理合成途径。[CpFe(μ,η-P)]（A）与低价过渡金属阳离子的组合产生了一系列三层夹心配合物[CpFe(μ,η-P)MCp'''][WCA]（M = Cr - Ni；WCA = 弱配位阴离子，Cp''' = 1,2,4-BuCH）。相反，利用芳烃配合物[M(CR)][WCA]（M = Fe，Co）可以合成前所未有的含磷四层夹心配合物[{Cp*Fe(μ,η-P)}M][]（M = Fe，Co）。
