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: A mixture of Tetrakis(acetonitrile)copper(I) tetrafluoroborate ([Cu(NCCH3)4]BF4, 3.11 g, 33.0 mmol) and Bis[(2-diphenylphosphino)phenyl]ether (O[C6H4P(C6H5)2]2, DPEphos, 5.33 g, 33.0 mmol) in 300 ml of CH2Cl2 was stirred at room temperature for 3 h. Upon addition of 1,10-Phenanthroline (C12H8N2, phen, 1.78 g, 33.0 mmol) the clear solution turned bright yellow, remained clear, and was stirred for an additional 2 h. Approximately 900 ml of diethyl ether ((CH3CH2)2O) was added to the solution to precipitate a bright yellow solid. The solution containing the newly precipitated solid was then left in the refrigerator for one day. It was vacuum filtered using a medium frit, washed with diethyl ether and dried under vacuum. A bright yellow powder was isolated (yield: 8.00 g, 93 percent)., 166330-10-5
