Purity/Quality: 98% Triphenylsilanol
Safety Information:
• Pictogram(s):
Xi
• Hazard Codes: Xi
• Statements:36/37/38
• Safety Statements:26-36
Useful:
• Chemical Properties White crystal solid or powder
• 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.
