Abstract
Organoaminosilanes, such as without limitation di-iso-propylaminosilane (DIPAS), are precursors for the deposition of silicon containing films such as silicon-oxide and silicon-nitride films. Described herein are methods to make organoaminosilane compounds, or other compounds such as organoaminodisilanes and organoaminocarbosilanes, via the catalytic hydrosilylation of an imine by a silicon source comprising a hydridosilane.
