Quantum chemical calculations of the reaction of hexamethyldisilazane with silica indicates a two-step mechanism. The first, rate-determining step results in trimethylsilylation of a surface silanol and formation of trimethylaminosilane. The second step involves reaction of a trimethylaminosilane re
