• Regioselective [2+2+2] cycloaddition of carboryne with alkynes to give benzocarborane compounds
• Kumada-Corriu cross coupling of Grignard reagents
• Borylation of aryl chlorides
• Reductive aldol cyclization-lactonization
• Arylcyanation of alkynes
• Alkynylation of benzonitriles via C-C bond activation
