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.
Copper(I) hexafluorophosphate (2.4 mg, 0.0064 mmol) and bis[2-(diphenylphosphino)phenyl]ether (3.4 mg, 0.0064 mmol) were stirred in dehydrated methylene chloride (2 mL) under an argon atmosphere at room temperature for 2 hours. A solution (1 mL) of the compound B4 (10.8 mg, 0.0064 mmol) in dehydrated methylene chloride was added to the reaction solution, the homogeneous reaction solution was stirred at room temperature for 1 hour, and the reaction solution was concentrated and dried to obtain the metal complex C5.1H NMR (300 MHz, CDCl3): delta 9.00 (s, 2H), 8.79 (s, 2H), 8.28 (s, 2H), 8.11 (s, 2H), 7.91 (s, 4H), 7.86 (s, 8H), 7.70 (d, J=7.2 Hz, 16H), 7.52 (d, J=7.2Hz, 16H), 6.95 (br, 20H), 6.89-6.80 (m, 4H), 6.74 (br, 2H), 6.69 (br, 2H), 1.38 (s, 36H).31P NMR (122 MHz, CDCl3): delta-8.82.The metal complex C5 emitted yellow light under ultraviolet excitation (365 nm), the emission peak wavelength was 572.5 nm, and the excitation lifetime was 1.4 mus.The metal complex C5 was easily dissolved in chloroform, toluene, and xylene at room temperature.When the metal complex C5 was left to stand in air at 100¡ã C. for 7 hours, change in emission intensity was hardly observed., 166330-10-5
The synthetic route of 166330-10-5 has been constantly updated, and we look forward to future research findings.
