9,9′-Bis-o-carboranes: synthesis and exploration of properties†
Abstract
A highly efficient Pd-catalyzed B(9)–H/B(9)–H oxidative dehydrogenation coupling of carboranes to synthesize 9,9′-bis-o-carboranes has been developed. The properties and derivatization of 9,9′-bis-o-carborane were also examined, which provided diverse bis-o-carborane derivatives and bis-nido-carborane.
