硫醇根桥联的铑和铱配合物可以很容易地实现H2在金属-硫键上的异裂，生成相应的氢化物桥联配合物。此外，末端炔可以插入Rh-H-Rh片段，形成σ：π链烯桥连配合物，然后在还原剂和酸的存在下转化为相应的烯烃。
Thiolate-bridged dirhodium and diiridium complexes can facilely realize heterolytic cleavage of H2 across the metal-sulfur bond to generate the corresponding hydride bridged complexes. Furthermore, terminal alkynes can insert the Rh-H-Rh fragment to afford σ:π alkenyl bridged complexes and then convert to the corresponding alkenes in the presence of a reductant and an acid.
