• Application: Triphenylsilane serves a multifaceted role in organic synthesis, primarily functioning as a reactant and reagent in various chemical transformations. Its versatile applications include the preparation of triphenylsilyl ethers, which are crucial for the protection of alcohol groups due to their exceptional stability against acidic hydrolysis. Furthermore, it is employed for catalytic hydrogen-deuterium exchange reactions, oxidation processes involving carbon nanotube-gold nanohybrids, and the hydrolysis of silanes using ruthenium complexes. Additionally, triphenylsilane is instrumental in hydrosilylation reactions for the creation of enolsilanes, the synthesis of bromosilanes, and the production of α-O-silylated acyloin derivatives via ozone oxidation of silyl-alkenes. It is a remarkably effective reductant, surpassing trialkylsilanes in reducing organic halides and offering significant selectivity in the conversion of cyclic hemiacetals and the transformation of O-acetyl furanoses and pyranoses into deoxy sugars. Moreover, triphenylsilane facilitates the synthesis of hexaphenyldisiloxane and tristriphenylsilylbismuth through reactions involving aqueous alkali and triethylbismuth, respectively.
