13991-08-7, 1,2-Bis(diphenylphosphino)benzene is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a MeCN (20 mL) solution of precursor A (106 mg, 0.229 mmol) was added Me3NO¡¤2H2O(65 mg, 0.58 mmol) under N2, resulting in a color change from red to brown, and stirred atroom temperature for about 20 min. A solution of dppbz (120 mg, 0.269 mmol) in MeCN(20 mL) was added to the above brown solution through a catheter and the resulting solutionwas stirred at room temperature for about 2 h and then reuxed at 60 C for about 12 h. Thereaction was monitored by IR spectroscopy to ensure completion. Upon removing the solventunder reduced pressure, the crude product was puried by chromatography on silica gelusing CH2Cl2/petroleum ether (v/v = 4:5) as eluent. Complex 1 was collected as a green solid(72 mg, 33%). IR (KBr disk, cm-1): nuC?O 2019 (vs), 1953 (vs), 1905 (v). 1H NMR (400 MHz, CDCl3,ppm): 1.68 (t, 2 H, 2JHaHe = 3JHaHa? = 12.6 Hz, 2 SCHaHe), 2.03 (m, 1 H, CH), 2.34 (d, 2 H,2JHeHa = 12.4 Hz, 2 SCHaHe), 6.18 (d, 2 H, Ph), 7.03 (m, 3 H, Ph), 7.21-7.26 (m, 8 H, Ph), 7.35-7.42(m, 10 H, Ph), 7.73-7.76 (m, 6 H, Ph). 31P NMR (161.9 MHz, CDCl3, 85% H3PO4, ppm): 88.2 (s).Anal. Calc. for C43H34Fe2O4P2S2: C, 60.58; H, 4.02. Found: C, 60.31; H, 4.30.
