In the present work, the effective method for the synthesis of new 1,7-bis[chloro(organo)siloxanylmethyl]-m-carboranes from bis(brommagnesium methyl)-m-carborane and chloro(organo)siloxanes: 1,7-bis[chloro-1,1,3,3-tetramethyl-disiloxanylmethyl]-m-carborane (I), 1,7-bis[chloro-1,1,3,3,5,5-hexamethyl-trisiloxanylmethyl]-m-carborane (VII) and 1,7-bis[chloro-1,1,3,3,5,5,7,7-octamethyltetra-siloxanylmethyl]-m-carborane (XIII) with yields up to 85% was developed. The use in the reaction of other (organo)siloxanes with different radicals at silicon atoms allowed to obtain the corresponding chloro(organo)siloxanes: 1,7-bis[chlorotetraorgano-disiloxanilylmethyl]-m-carboranes (II-VI), 1,7-bis [chlorohexaorgano-trisiloxanylmethyl]-m-carboranes (VIII-XII) and 1,7-bis [chlorooctaorgano-tetrasiloxanylmethyl]-m-carboranes (XIV-XVIII) with yields up to 85% and expand the range of new promising products that are well soluble in organic solvents.
