With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.166330-10-5,(Oxybis(2,1-phenylene))bis(diphenylphosphine),as a common compound, the synthetic route is as follows.
General procedure: DPEphos (0.1077 g, 0.2 mmol) and dppe (0.0396 g, 0.1 mmol) were dissolved in the mixture of CH2Cl2, CH3OH (10 ml, v/v = 1/1), adding AgCl (0.0286 g, 0.2 mmol) and DMF (2 ml) into the reaction flask. Stirring for 12 h, and then filtrating, the filtrate was slow evaporated at ambient temperature. 16 days later, colorless block shaped crystals were obtained. Yield: 22.5percent (0.0427 g). Anal. Calc.for (C103H95Ag2Cl2NO5P6): C, 65.14; H, 5.01; N, 0.74. Found: C,65.45; H, 4.94; N, 0.74percent. IR (cm-1, KBr pellets): 3436br, 3050m, 2924m, 2853m, 1950w, 1676vs, 1583m, 1565m, 1480s, 1461s, 146vs, 1385s, 1330m, 1311m, 1257s, 1223s, 1184m, 1161m, 1127m, 1094s, 1070s, 1026m, 997m, 878m, 801m, 747s, 696s,543w, 529w, 506s, 481m, 470m, 433w, 420w. 1H NMR (600 MHz,CDCl3): 2.90 (d, 4H, dppe), 3.48 (s, 6H, DMF), 6.76?7.28 (m, 76H,Ph), 8.02 (s, 1H, DMF). 31P {1H}NMR (243 MHz, CDCl3): 5.7 (br,dppe), 11.9 (br, d, JAg?P = 286.8 Hz, DPEphos)., 166330-10-5
166330-10-5 (Oxybis(2,1-phenylene))bis(diphenylphosphine) 4285986, achiral-phosphine-ligands compound, is more and more widely used in various.
