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
The complex RuCI2(CO)(dmf)(PPh3)2 (200 mg, 0.25 mmol, 1 equiv) dissolved in CH2CI2 (2 mL) was reacted with the ligand dppf (160 mg, 0.29 mmol, 1 .2 equiv) at room temperature for 2 h. The ligand en (15 muL, 0.37 mmol, 1.5 equiv) was then added and the mixture was stirred at room temperature for 2 h. The solution was concentrated to about 0.5 mL and the complex was precipitated by addition of n-heptane (10 mL). The obtained solid was filtered and thoroughly washed 4 times with ethyl ether (3 mL) and dried under reduced pressure. Yield: 180 mg (88percent). Anal. Calcd (percent) for C37H36CI2FeN2OP2Ru: C, 54.56; H, 4.46; N, 3.44, Found: C, 54.50; H, 4.51 ; N, 3.47. 1H NMR (200 MHz, CD2CI2) delta 7.97 – 7.24 (m, 20H), 5.59 (s, 2H), 5.15 – 4.91 (m, 2H), 4.53 (s, 2H), 4.20 (s, 2H), 3.97 (s, 2H), 3.68 – 3.42 (m, 2H), 2.58 – 2.41 (m, 2H), 2.14 – 1 .85 (m, 2H). 13C NMR (50 MHz, CD2CI2) delta 204.0 (t, J = 14.8 Hz), 135.9 (t, J = 5.7 Hz), 134.2, 134.1 (d, J = 10.1 Hz), 133.4, 132.9 (t, J = 4.7 Hz), 132.0, 130.7, 130.4 (d, J = 2.4 Hz), 129.2 – 128.3 (m), 77.8 (t, J = 4.9 Hz), 75.7 (t, J = 3.2 Hz), 73.5 (t, J = 3.3 Hz), 71 .3 (t, J = 3.0 Hz), 45.7. 31 P NMR (81 .0 MHz, CD2CI2) delta 39.8.
