developed for the obtaining of new oligo(dimethyl)silanes comprising 1,7-bis(methyl)-m-carboranyl units and bearing the terminal chlorosilyl or methoxysilyl groups. Reactions of such oligomers with an excess of benzylmagnesium chloride or 1-chloromagnesiummethyl-m-carborane lead to oligo-m-carboranylenemethylenesilanes containing the terminal benzylsilyl or m-carboranylmethylenesilyl groups. The novel
