What is Triphenylvinylsilane?
Chemical properties
off-white to slightly beige crystalline powder
The Uses of Triphenylvinylsilane
Triphenylvinylsilane can be used to produce triphenyl-[2-(tetrahydro-furan-2-yl)-ethyl]-silane at temperature of 190°C. This reaction will need reagent di(t-butyl)peroxide with reaction time of 2 hours. Also employed as an organic light emitting diode.
Purification Methods
It has been recrystallised from EtOH, 95% EtOH, EtOH/*C6H6, pet ether (b 30-60o) and Et2O, and has been distilled under reduced pressure. [Cason & Brooks J Am Chem Soc 74 4582 1952, Nagel & Post J Org Chem 17 1379 1952, Beilstein 16 IV 1371.]
