| | Triphenylsilane Usage And Synthesis |
| Chemical Properties | Triphenylsilane is Off-white solid
| | Uses | Triphenylsilane acts as a reactant or reagent for catalytic hydrogen deuterium exchange reactions of silanes, to be oxidized by carbon nanotube-gold nanohybrids, for hydrolysis by ruthenium complexes, for hydrosilylation to produce enolsilanes, for synthesis of bromosilanes, for ozone oxidation of silyl-alkenes for synthesis of α-O-silylated acyloin derivatives. It is used to synthesize hydrido silyl and bis(silyl) bis(imidazolinylidene) nickel complexes. | | Application | More effective radical-based reagent for reduction of
organic halides than the trialkylsilanes. Compares
well with tri-n-butyltin hydride in reduction of enones to
ketones. Shows good selectivity in the reduction of cyclic
hemiacetals. Converts O-acetyl furanoses and pyranoses
to deoxy sugars. | | Preparation | 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 AlH3
This reaction is typically carried out in anhydrous conditions and under inert gas atmosphere. | | Purification Methods | Purify it by recrystallisation from MeOH.
