Copper-Catalyzed Defluorinative C(sp3)–C(sp2) Cross-Coupling of Polyfluoroarenes with gem-Diborylalkanes
A divergent copper-catalyzed defluorinative C(sp3)–C(sp2) cross-coupling of gem-diborylalkanes with polyfluoroarenes has been developed through a synergistic ligand/base-controlled strategy. Various fluorinated aromatic compounds were obtained in moderate to excellent yields. Late-stage modification of bioactive molecules, gram-scale reaction, and versatile downstream derivatization demonstrated the application value of this protocol. Preliminary mechanistic studies hinted that this transformation is a SNAr mechanism rather than a radical pathway.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
