| | 1,1,2,2-TETRAPHENYLDISILANE Usage And Synthesis |
| 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. |
