Here we present a catalytic system for the copper catalysed arylation of phenols with aryl halides. Bidentate N‐heterocyclic carbene ligands provide a well‐defined catalytic system that enable low loading of copper in effective coupling reactions (0.5 mol% Cu or lower). The reaction scope of aryl iodides and aryl bromides is developed, that is tolerant of functional groups and a library of biaryl ethers with lead‐like properties is prepared. The presence of excess ligand (in a 1:3 ratio) is shown to be optimal to prevent catalyst degradation, presumably by avoiding decomplexation of the ligand. This is also supported by the catalytic results obtained with pre‐formed copper complexes. The kinetics of the reaction are examined and shown to be first order in copper, supportive of a well‐defined catalyst species, first order in phenol and aryl iodide, and zero order in base under the developed conditions. Computational studies performed using Minnesota MN15‐L parametrisation method support an oxidative addition–reductive elimination pathway. Reductive elimination would be turnover limiting and occurr through an intimate ion pair intermediate.","PeriodicalId":118,"journal":{"name":"Advanced Synthesis & Catalysis","volume":"80 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the stereoconvergent synthesis of Z‐allylic boronates was realized with protoborylation of E/Z‐mixed 1,3‐dienes catalyzed by a novel copper‐guanidine complex. The reaction could proceed smoothly under very mild conditions with good functional group tolerance, and convert diverse aryl‐substituted 1,3‐dienes into the desired Z‐1,4‐addition products with excellent chemo‐, regio‐, and stereoselectivities in minutes. Detailed mechanistic studies also helped to disclose the origin of stereoconvergency.

This one-step sulfonamide synthesis exhibits excellent reactivity toward highly electron-deficient and less nucleophilic anilines as well as aminopyridines while tolerating a wide range of functional groups. In addition to the desired sulfonamide target, we also isolated an ionic salt as the sole side product from the reaction mixture that has been identified as bis[1-methyl-1H-imidazole-3-ium] hexafluorosilicate (IV). The glass surface of reaction vessel is acting as the source of silicon present in the isolated side product. Formation of hexafluorosilicate salt is also facilitating the consumption of sulfonyl fluoride for sulfonamide synthesis. Optimization of the reaction under various conditions, as well as the isolation of the bis[1-methyl-1H-imidazole-3-ium] hexafluorosilicate (IV) salt, highlight the crucial role of N-methylimidazole and support the glass-assisted approach. Besides the first example of glass-assisted SuFEx catalyzed by benign organic bases, this reaction also offers an alternative route for accessing protic hexafluorosilicate-based molten salts without employing external HF. The synthetic utility of this SuFEx route for late-stage functionalization is also demonstrated.","PeriodicalId":118,"journal":{"name":"Advanced Synthesis & Catalysis","volume":"64 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142589152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
