Dithiodiolate ligands were synthesized by reacting 1,2-ethanedithiol or 1,2-benzenedithiol with 2,2-bis(trifluoromethyl)oxirane, led selectively to mononuclear octahedral group 4 complexes of the type [{OSSO}M(OR)(2)], which features C(2) symmetry and fluxional behavior, and were highly active in the ring-opening polymerization of rac- and L-lactide.
二硫代二醇配体是通过 1,2-乙二硫醇或 1,2-苯二硫醇与 2,2-双(三氟甲基)环氧乙烷反应合成的，选择性地得到单核八面体第 4 族配合物[{OSSO}M(OR)(2)]，其具有 C(2)对称性和流动性，并在 rac-和 L-丙交酯的开环聚合中具有很高的活性。
