12150-46-8, 1,1-Bis(diphenylphosphino)ferrocene is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Ru(acac)2(CH3CN)2 (0.100 g, 0.262 mmol) and 1,1-bis(diphenylphosphino)ferrocene (dppf) (0.145 g, 0.262 mmol) were dissolved in 40 mL of toluene and refluxed under an argon atmosphere for 8 h. After the refluxing was complete, the solvent was removed under vacuum. Slow diffusion of petroleum ether vapor into a CH2Cl2 solution of Ru(acac)2(dppf) afforded the desired yellow crystal. Yield 91percent, 0.203 g. Anal. Calcd (percent) for RuFeC44H42O4P2: C, 61.91; H, 4.96. Found: C, 61.85; H, 4.99. ESI-MS (CH3CN): m/z 854.1 [M+H]+.
