An efficient method for the synthesis of organosilicon compounds containing m -carboranylmethyl was developed, which afforded the products in good to excellent yields (up to 88%) compared to the literature methods affording a 38% yield. Moreover, the generated intermediate 5 containing a Si-Br bond could be functionalized conveniently. A method for synthesizing bis(silymethyl)- m -carborane has been developed, the yield was reached up to 88%. The intermediate Si-Br compound could be functionalized, Si-OH, Si-vinyl, Si-ethynyl and Si-H of bissilylmethyl- m -carborane were synthesized.
