Palladium-Catalyzed Selective B(3)-Esterification of o-Carboranes with CO and Alcohols
Selective functionalization of o-carboranes has received tremendous attention, specifically in the regioselective modification of the ten chemically similar BH vertices within o-carborane cage. We disclose herein a strategy for palladium-catalyzed esterification of the B(3)–H bond in o-carboranes using tungsten hexacarbonyl as a carbon monoxide source. The corresponding functionalized o-carboranes were prepared in moderate to very good yields with excellent regioselectivity.
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.
