ABSTRACT:
A process for synthesizing an aminosilane compound such as bis(tertiarybutylamino)silane is provided. In one aspect of the present invention, there is provided a process for making bis(tertiarybutylamino)silane comprising reacting a stoichiometric excess of tert-butylamine with dichlorosilane under anhydrous conditions sufficient such that a liquid comprising the bis(tertiarybutylamino)silane product is produced.
