13991-08-7, 1,2-Bis(diphenylphosphino)benzene is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Under argon atmosphere, 1,2-bis(diphenylphosphino)benzene (34.6 mg, 0.0776 mmol) was added to 5 mL of the solution of silver(I) tetrafluoroborate (15.1 mg, 0.0776 mmol) in dichloromethane, and the mixture was stirred at room temperature for 30 minutes. Then, 2,9-dichloro-1,10-phenanthroline (23.2 mg, 0.0931 mmol) was added to the reaction solution, which was heated to reflux with stirring for two hours. The reaction solution was filtrated, and the filtrate was concentrated, subjected to recrystallization by slow diffusion of dichloromethane-ether, and dried to provide 46.0 mg of the yellow solid complex. [Show Image] The NMR data of the obtained complex is provided below. 1H NMR (300 MHz, CDCl3) delta 8.80 (d, J = 8.1 Hz, 2H), 8.24 (s, 2H), 8.15 (d, J = 8.1 Hz, 2H), 7.62-7.51 (m, 4H), 7.39-7.29 (m, 20H); 31P NMR (122 MHz, CDCl3) delta -4.4 (d, J (31P-107Ag, 109Ag) = 325, 373 Hz). The composition of the obtained complex was determined according to the same method as in Example 15. The present complex corresponds to the above composition formula (5).
13991-08-7, As the paragraph descriping shows that 13991-08-7 is playing an increasingly important role.
