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
To a dichloromethane solution (20 mL) of 1a (20 mg, 0.06 mmol) and dppf (35 mg, 0.06 mmol) was added dropwise a CH2Cl2 solution (10 mL) of Me3NO (5 mg, 0.07 mmol) over a period of 30 min and stirred for an additional 5 h at room temperature. The reaction mixture was then filtered through a short silica column (4 cm). The solvent was removed under reduced pressure and the residue chromatographed by TLC on silica gel. Elution with cyclohexane/dichloromethane (3:7, v/v) developed four bands. The first and second bands were unreacted dppf and phenazine, respectively. The third gave Fe(CO)2) (kappa1-dppf) (eta4-C12H8N2) (5a) (21 mg, 40percent) while the fourth band afforded a trace amount of material insufficient for characterization. Spectral data for 5a: IR (nuCO, CH2Cl2): 1994(vs), 1941(vs) cm-1. 1H NMR (CDCl3): delta 7.43 (m, 20H), 7.23 (m, 4H), 5.91 (m, 2H), 4.45 (m, 2H), 4.22 (m, 2H), 3.86 (m, 2H), 3.70 (m, 2H), 3.06 (m, 2H). 31P{1H} NMR (CDCl3): delta 61.0 (s, 1P) -18.1 (s, 1P). Anal. Calcd. for C48H36Fe2N2O2P2: C, 68.11; H, 4.29; N, 3.31. Found: C, 68.31; H, 4.42; N, 3.46percent.
