Synthesis of B-organyl-o- and -m-Carboranes by the Cross Coupling of B-Iodo-o- and -m-Carboranes with Organozinc Compounds, Catalyzed by Palladium Complexes

Zakharkin,Ol'shevskaya,Zhigareva

, p. 925 - 927 (2007/10/03)

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.
