| | Triphenylsilane Usage And Synthesis |
| Chemical Properties | Triphenylsilane is an off-white solid that is soluble in most organic solvents. It is used in certain cases for the preparation of triphenylsilyl ethers, which serve as alcohol-protecting groups. The triphenylsilyl group is considerably more stable (about 400 times) than the TMS group toward acidic hydrolysis. | | 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.
Hexaphenyldisiloxane can be conveniently made by the action of aqueous alkali on triphenylsilane, Ph3SiH.
Tristriphenylsilylbismuth, (Ph3Si)3Bi, is made similarly from triethylbismuth and triphenylsilane: Et3Bi+3Ph3SiH==Heat==(Ph3Si)3Bi+3EtH. | | 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. | | reaction suitability | reagent type: reductant | | storage | This reagent is stable in the air. Because the toxicogical properties are unknown, it should be handled in a well-ventilated fume hood. Contact with the eyes and skin should be avoided. | | Purification Methods | Purify it by recrystallisation from MeOH.
