Thisnprocess is based on the ability of Pd to promote both the β-carbonnelimination of a bifunctional cyclobutanol precursor and the C–Cncoupling process with the resulting Pd-alkyl intermediate. Consequently,nnovel polyketone materials are obtained. Owing to the modular synthesisnof the used cyclobutanol monomers, the present ROP reaction allowsnthe introduction of substitution patterns in the polymeric chain thatnare not accessible by current polyketone synthesis methodologies.nWe have explored in detail the initiation, propagation, and terminationnsteps of this new polymerization process.","PeriodicalId":522887,"journal":{"name":"Figshare","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147905527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
