Abstract Transition metal-mediated B–H functionalization of carboranes has drawn increasing interests during the last two decades. This review describes how to incorporate B–H functionalization into the derivation of half-sandwich transition metal complexes containing o-carborane dichalcogenolates. The detailed mechanistic elucidations for metal-induced versatile B–H functionalization are also reviewed. Examples of selective B–H activation, stepwise B–H functionalization, cobalt-mediated B–H functionalization as well as dimetal-mediated B–H activation of o-carborane are discussed.
