Lithium o-carborane and lithium m-carborane react with C6F6 to give the bis-o- and bis-m-car-borane derivatives RCB10H10CC6F4CB10H10CR, while with C6F5C1 they react to give predominantly the monosubstituted derivatives RCB10H10CC6F4Cl.
Exchange of the chlorine atom by lithium occurs when butyllithium reacts with RCB1H10CC6F4Cl, with the formation of RCB10H10CC6F4Li.
