合成了含膦配体的新型硫醇桥联双核钌配合物[Cp*Ru{PhP（C6 H4-o-S）2}RuCp*]（OTf）2，[CpRu{PhP（C6 H4-o-S）2}RuCp*（OH 2）]（OTf）2和[Cp*Fe{PhP（C6 H4-o-S）2}RuCp*]（OTf）2，并通过X-射线分析进行了表征.这些双核配合物作为有效的催化剂，通过丙二烯叉配合物作为关键中间体，以良好至高产率将炔丙醇与2-丙醇进行炔丙基还原，得到相应的炔。
Novel thiolate-bridged dinuclear ruthenium complexes bearing a phosphine ligand, [Cp*Ru{PhP(C6H4-o-S)2}RuCp*](OTf)2, [CpRu{PhP(C6H4-o-S)2}RuCp*(OH2)](OTf)2, and [Cp*Fe{PhP(C6H4-o-S)2}RuCp*](OTf)2, are prepared and characterized by X-ray analysis. These dinuclear complexes work as effective catalysts toward propargylic reduction of propargylic alcohols with 2-propanol via allenylidene complexes as key intermediates to give the corresponding alkynes in good to high yields.
