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
A benzene solution (20mL) of 1 (50mg, 0.074mmol) and dppb (33mg, 0.074mmol) was refluxed for 5h. The solvent was removed under reduced pressure and the residue was chromatographed by TLC on silica gel. Elution with n-hexane/CH2Cl2 (7:3 v/v) developed two bands in addition to intractable, presumably decomposed, material. The faster moving band gave [ Fe4(CO)10 (mu3-Te)4 (kappa2-dppb)] (8) (13mg, 12%) as black crystals and the second band afforded [Fe3(CO)8(mu3-Te)2(kappa2-dppb)] (4) (20mg, 25%) as red crystals after recrystallization from hexane/CH2Cl2 at 4C. Characterization data for 4: IR (nu(CO), CH2Cl2): 2042s, 2021s, 1998vs, 1964s cm-1. 1H NMR (CDCl3): delta 7.70-7.67 (m, 4H), 7.59-7.34 (m, 10H), 7.24-7.03 (m, 10H). 31P{1H} NMR (CDCl3): delta 74.2 (s). ESI-MS: m/z 1093.24 (M+, calc. 1093.27). Characterization data for 8: IR (nu(CO), CH2Cl2): 2053s, 2029vs, 1977s, 1908w cm-1. 1H NMR (CDCl3): delta 7.67-7.04 (m, 24H). 31P{1H} NMR (CDCl3): delta 53.5 (s). ESI-MS: m/z 1460.33 (M+, calc.1460.34).
13991-08-7, 13991-08-7 1,2-Bis(diphenylphosphino)benzene 498379, achiral-phosphine-ligands compound, is more and more widely used in various fields.
