Herstellung & Synthese

synthetische

Triphenylsilane can be synthesized by reducing phenylsilane (PhSiH3) with a reducing agent such as lithium aluminum hydride (LiAlH4). The overall reaction equation is as follows:3 PhSiH3 + 2 LiAlH4 → C18H16Si + 2 LiH + 2 AlH3This reaction is typically carried out in anhydrous conditions and under inert gas atmosphere.
