Abstract

We studied the ammonolysis of boron-substituted chlorosilylmethyl ortho-carborane derivatives and co-ammonolysis with trimethylchlorosilane. The reaction affords carboranylmethyl(organo)silanes with terminal aminosilane or trimethylsilyl groups. During ammonolysis, the bulky carboranylmethyl groups hinder the intermolecular condensation of intermediate products with aminosilane groups and favors the formation of low-molecular-weight organosilazanes not only from mono- and dichlorosilanes, but also from carboranylmethyltrichlorosilane. The Ccarborane-H groups having the acidic nature were found to be possibly involved in the formation of oligo(carboranylmethyl)silsesquiazane structure and its room-temperature structuring products.
