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
A benzene solution (20mL) of 1 (100mg, 0.148mmol) and dppf (82mg, 0.148mmol) was refluxed for 45min. The solvent was removed under reduced pressure and the residue was chromatographed by TLC on silica gel. Elution with n-hexane/CH2Cl2 (3:1 v/v) developed two bands. The faster moving band gave a very dark solid, tentatively assigned as [Fe3(CO)9(mu3-Te)2(kappa1-dppfO)] (15mg, 9percent), and the second band afforded [Fe3(CO)8 (mu3-Te)2 (kappa2-dppf)] (6) (60mg, 35percent) as red crystals after recrystallization from hexane/CH2Cl2 at 4¡ãC. Characterization data for [Fe3(CO)8(mu3-Te)2(kappa1-dppfO)]: IR (nu(CO), CH2Cl2): 2053s, 2039vs, 2010vs, 1996 vs, 1964s cm?1. 1H NMR (CDCl3): delta 8.23?7.43 (m, 20H), 4.4?4.38 (m, 4H), 3.35?3.31 (m, 4H). 31P{1H} NMR (CDCl3): delta 51.0 (s), 28.0 (s). Characterization data for 6: IR (nu(CO), CH2Cl2): 2039s, 1998vs, 1963s, 1951mcm?1. 1H NMR (CDCl3): delta 7.60?7.43 (m, 8H), 7.4?7.43 (m, 12H), 4.47 (s, 4H), 4.38 (s, 4H). 31P{1H} NMR (CDCl3): delta 51.2 (s). ESI-MS: m/z 1145.47 (M+, calc. 1145.35).
