The Suzuki cross-coupling reaction between readily available o-carboranyl-substituted pyridyl halides and (hete- ro)arylboronic acids under Pd catalysis has been developed, providing access to o-carboranyl biaryls in yields of 35%~92%. The transformations proceed under mild conditions and with high functional group tolerance using commercially available coupling partners. Furthermore, the Buchwald-Hartwig reaction and Sonogashira reaction of o-carboranyl pyridyl halides are reported as well, leading to the facile synthesis of o-carboranyl aminopyridines and alkynylpyridine derivatives, respectively. It is believed that these heteroarylated carborane derivatives may find applications in luminescent materials and drug discovery.

Key words: carborane, carboranyl pyridyl halides, cross coupling, palladium catalysis
