-Butyl-substituted diphospha[2]ferrocenophane was used as a stereochemically confined diphosphane to investigate the addition of various dichalcoganes (R2Ch2; Ch = S, Se, Te and R = Me, Ph). Bischalcogenophosphinous acid esters bearing four soft donor sides were obtained as a mixture of and diastereomers and characterized by means of multinuclear NMR and X-ray analysis. The coordination chemistry of multidentate ligand was explored toward d coinage metal centers (Cu(I), Ag(I), and Au(I)), yielding various bimetallic complexes.

-丁基取代的二磷杂[2]二茂铁烯被用作立体化学受限的二膦，以研究各种二硫属元素化合物（R2Ch2；Ch = S、Se、Te且R = Me、Ph）的加成反应。得到了具有四个软供体侧的双硫属元素次膦酸酯，它是一对非对映异构体的混合物，并通过多核核磁共振和X射线分析对其进行了表征。研究了多齿配体与d族货币金属中心（Cu(I)、Ag(I)和Au(I)）的配位化学，得到了各种双金属配合物。
