A new protocol for regioselective nucleophilic cage B-H substitution in o-carboranes has been proposed that is complementary to the strategies of transition metal catalysis and electrophilic substitution. Magnesium-mediated site-selective nucleophilic cage B(3,6)-H and B(9)-H substitution reactions of o-carboranes give a series of B(3,6)-dialkylated and B(9)-alkylated/arylated o-carboranes in high yields. Both steric and electronic factors of cage C substituents play crucial roles in controlling the site selectivity.

The cross coupling of 9-iodo- and 9,12-diiodo-1,2-carboranes, and 9-iodo- and 9,10-diiodo-1,7-carboranes with organozinc compounds, catalyzed by palladium complexes, leads to substitution of the iodine atom linked boron atom by an organic group to yield 9-organyl- and 9,12-diorganyl-1,2- carboranes, and 9-organyl- and 9,10-diorganyl-1,7-carboranes, respectively.

A convenient new method is proposed for the synthesis of 9-organo-substituted o- and m-carboranes and 2-organo-substituted p-carborane by the substitution of iodine in 9-iodine-o, 9-iodine-o-m, and 2-iodine-p-carboranes by an organic group from an organomagnesium compound in the presence of catalytic amounts of phosphine complexes of palladium.For the first time the halogen in boron halogen carboranes has been substituted by an organic group.
