DFT calculations revealed similar electronic transitions at 259 nm (π → π*) and 333 nm (n → π*), dominated by specific HOMO to LUMO transitions for [Pd(AD1Me)] and [Pd(AD1F)] with minor effects from substituents. [Pd(AD1F)] demonstrated catalytic activity in copper-free Sonogashira coupling, achieving a TOF of 2.4 h<sup>−1</sup> and a TON of 7.1 at 120 °C. Its higher ionization potential and lower electron affinity, as determined by DFT, support its superior catalytic performance compared to [Pd(AD1Me)].</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"176 ","pages":"Article 114186"},"PeriodicalIF":4.4,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143548853","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}
