| Triphenylsilanol Usage And Synthesis |
| Chemical Properties | White crystal | | Uses | Triphenylsilanol is used as a water surrogate for regioselective Pd catalyzed allylations. A thick on germanium substrates have been produced by the electron bombardment of an evaporated thin film of triphenylsilanol. | | Definition | ChEBI: An organosilanol in which silicon is bonded to a single hydroxy function and to three phenyl groups. | | Purification Methods | It is purified by dissolving in pet ether, passing through an Al2O3 column, eluting thoroughly with CCl4 to remove impurities and then eluting the silanol with MeOH. Evaporation gives crystals with m 153-155o. It can be recrystallised from pet ether, CCl4 or from *benzene or Et2O/pet ether (1:1). It has also been recrystallised by partial freezing from the melt to constant melting point.
