A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2. In a Article，once mentioned of 12150-46-8, COA of Formula: C34H28FeP2
Treatment of the platinum(0) complex [Pt(dppf)(nbe)] [1; dppf = 1,1?-bis(diphenylphosphanyl)ferrocene, nbe = norbornene] with the 1,2-dihydrodisilanes HPh2SiSiPh2H or HMe2SiSiMe2H gave [Pt(SiR2H)2(dppf)] (2, R = Ph; 4, R = Me) by oxidative addition of the Si-Si bond. The bis-silyl complexes 2 and 4 react with H2 to give [Pt(H)(SiR2H)(dppf)] (3, R = Ph; 5, R = Me) and H2SiR2. Adding HPh2SiSiPh2H to the hydrido silyl complex 3, which can also be prepared through Si-H activation of H2SiPh2 at 1, resulted in the regeneration of 2 as well as in the release of H2SiPh2. Treatment of HR2SiSiR2H with H2 (1.7 bar) in the presence of 2 or 4 under moderate conditions led to the catalytic formation of H2SiR2 with TONs up to 25. The catalytic conversions are distinguished by a high selectivity for the hydrogenolysis of the 1,2-dihydrodisilanes, and no significant tendency for redistribution reactions at Si was observed.
