Abstract
Following the successful construction of nitrilium/pyridinium and sulfonium salts, the Chan–Lam coupling has been significantly advanced with the first demonstration of quaternary phosphonium salt synthesis. We present a method employing copper(II) acetate in trifluoroethanol to efficiently produce a range of aryl and vinyl phosphonium salts from boronic acids, including those derived from complex natural products, thus overcoming phosphine oxidation issues and expanding the scope to functionalized phosphorus.
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.
