Ethynylferrocene (FcC≡CH) was utilized as a redox-active metalloligand for the synthesis of polynuclear coinage metal complexes. The reaction of [FcC≡CLi] with tri- tert-butylphosphine metal chlorides [BuP-MCl] (M = Au, Ag, Cu) yielded different heteronuclear ferrocene-funtionalized alkyne complexes featuring metallophilic interactions. Furthermore, the redox properties of the ferrocenyl-functionalized tetracopper complex were investigated by cyclic voltammetry and UV-vis-near-IR spectroelectrochemistry. They indicate the compounds' redox-rich nature and a weak electronic coupling between the redox-active ferrocenyl units over a large distance.
二茂铁乙炔（FcC≡CH）被用作氧化还原活性金属配体，用于合成多核金属配合物。[FcC≡CLi]与三-叔丁基膦金属氯化物[BuP-MCl]（M = Au、Ag、Cu）反应生成具有金属亲合相互作用的不同杂核二茂铁功能化炔烃配合物。此外，通过循环伏安法和紫外可见近红外光谱电化学研究了二茂铁功能化四铜配合物的氧化还原性质。它们表明这些化合物具有氧化还原丰富的性质，并且在较大距离上氧化还原活性二茂铁单元之间的电子耦合较弱。
