With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13885-09-1,2-(Diphenylphosphino)biphenyl,as a common compound, the synthetic route is as follows.
A suspension of copper(I) iodide (0.042 g, 0.22 mmol) and dpbp (0.149 g, 0.44 mmol) in 15 mL ofCH2Cl2 was stirred for 3 h at room temperature to form a white precipitate. The precipitate was filteredoff and purified by recrystallization from CH2Cl2/aectonitrile to give colorless crystals (Yield: 0.160 g,84.2percent). 1H NMR (400 M, CDCl3) delta: 7.44?7.26 (m, 26H, m,p-Ph + ?PC6H4?), 7.09?6.99 (m, 12H, o-Ph). 13CNMR (100 M, CDCl3) delta: 147.87, 147.67, 140.24, 140.16, 134.31, 134.17, 133.45, 132.17, 131.81, 131.07,130.71, 130.14, 129.90, 128.93, 128.69, 127.93, 127.26 (Ar?C). 31P NMR (240 M, CDCl3) delta ?10.16 (s). Anal.Calcd for C48H38CuIP2: C, 66.48; H, 4.42. Found: C, 66.50; H, 4.40. MS (MALDI-TOF): m/z Calcd for [M?I]+,739.1745, found 739.1874.
As the paragraph descriping shows that 13885-09-1 is playing an increasingly important role.
