1,1,2,2-Tetraphenyldisilane Chemical Properties, Uses, Production
Physical properties
mp 79–80 °C
Uses
1,1,2,2-tetraphenyldisilane (TPDS) is more effective than pentamethyldisilane, since one phenyl group on the Si–H group probably reduces by 2 kcal/mol the Si–H bond dissociation energy. TPDS is used for radical reduction, intramolecular and intermolecular carbon–carbon bond formation, 1,2-elimination, etc., of halides, chalcogenides, and xanthates.
Preparation
generally, 1,1,2,2-tetraphenyldisilane is prepared by the coupling reaction of diphenylsilane in the presence of diphenyltitanocene without solvent under heating conditions at 110°Cfor 24 h.
