X-ray analysis revealed that in <b>I</b> both monoanionic amidinate ligands are κ<sup>3</sup>-N,N,O-coordinated to La(III) ion. Complex <b>I</b> demonstrates high catalytic activity in ring-opening polymerization of cyclic esters and enables 100% conversion of 100–300 equiv of <i>rac</i>-lactide in 30 min or 100–500 equiv of ε-caprolactone in 1 min providing highly controlled polymerization. The obtained polymeric samples feature linear dependence of molecular weight vs. the monomer loading and rather narrow polydispersity (<i>M</i><sub>w</sub>/<i>M</i><sub><i>n</i></sub> = 1.36–1.88).</p>","PeriodicalId":759,"journal":{"name":"Russian Journal of Coordination Chemistry","volume":"51 5","pages":"374 - 380"},"PeriodicalIF":1.1,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
