166330-10-5, (Oxybis(2,1-phenylene))bis(diphenylphosphine) is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a Schlenk flask containing Cu(CH3CN)4*BF4 (0.032g,0.1 mmol) and DPEphos (0.054g, 0.1 mmol) was added CH2Cl2 (10 mL) under nitrogen atmosphere, and the solution (i) was stirred at room temperature (RT) for 4 h. A CH2Cl2 (10 mL) and CH3OH (10 mL) mixture solution of NHPIP (0.034 g, 0.1 mmol) and KOH (0.006 g, 0.1 mmol) was also stirred at room temperature (RT) for 4 h to give solution (ii). Then, (ii) was added into (i) by a syringe under nitrogen. After reaction of 48 h at RT, the solution was filtered and the solventwas removed by a rotary evaporator. The residue was dissolved in diethyl ether, and orange block crystals were obtained by the solvent evaporation method (0.080 g, 85percent).
