Abstract: The Sonogashira cross coupling between the monocarborane cluster 12-ethynylmonocarba-closo-dodecaborate [CB11H11-12-CCH]- and bromoarenes under Pd catalysis has been developed, providing access to aryl carboranyl alkynes in yields of 42-95%. The transformations proceed under mild conditions and… read more here.
