Abstract
An efficient method for the synthesis of o(m)-carboranylmethylsiloxanes by the Grignard reaction from 1,2(7)-bis(bromomagnesiummethyl)-o(m)-carboranes and 1-chloro-1,1,3,3,3-pentamethyldisiloxane has been developed. As a result, 1-(1,1,3,3,3-pentamethyldisiloxanylmethyl)-2(7)-methyl-o(m)-carboranes, 1,2(7)-bis(1,1,3.3,3-pentamethyldisiloxanylmethyl)-o(m)-carboranes, exocyclic 1,2-(o-carborano)-4,6-bis(dimethylsilyl)-5-oxacycloheptane, 1,7-bis(chloro-1,1,3,3-tetramethyldisiloxanylmethyl)-m-carborane, and oligomer containing two 1,7-bis(dimethylsilylmethyl)-m-carborane units have been obtained.
