A series of bis(amidinate) tin(II) complexes is synthesized and shown to rapidly polymerize ε-caprolactone (ε-CL) in the presence and absence of benzyl alcohol giving high-molecular-weight poly(ε-CL) (M(n) up to 160,600 Da). Ligands having electron donating groups were found to accelerate the polymerization by making the complex more nucleophilic.
合成了一系列双（酰胺基）锡（II）配合物，并研究了它们在有/无苯甲醇存在下快速聚合 ε-己内酯（ε-CL）的情况，得到了高分子量的聚（ε-CL）（M(n)高达 160600 Da）。具有给电子基团的配体通过使配合物更具亲核性而加速聚合。
