The properties of a metal–carborate complex in a transmetalation step were important to achieve the cross-coupling process with aryl halides, and the use of lithiated monocarba-closo-dodecaborate was found to promote the carbon–carbon bond formation to provide a series of C-arylated monocarba-closo-dodecaborate derivatives. Mechanistic investigations with DFT calculations suggested the efficient transmetalation with the lithium reagent.
