1,1,2,2-TETRAPHENYLDISILANE Chemical Properties,Usage,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.
