With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.119-91-5,2,2′-Biquinoline,as a common compound, the synthetic route is as follows.
Under argon atmosphere, 1,2-bis(diphenylphosphino)benzene (91.7 mg, 0.205 mmol) was added to 5 mL of the suspension of silver(I) tetrafluoroborate (40.0 mg, 0.205 mmol) in dry dichloromethane, and the mixture was stirred at room temperature for one hour. Then, 2,2′-biquinoline (52.7 mg, 0.205 mmol) was added to the reaction solution, which was stirred at room temperature for another one hour. The pale yellow reaction solution was filtrated, and the filtrate was concentrated, subjected to recrystallization by slow diffusion of chloroform-ether, and dried to provide 171 mg of the pale yellow solid complex. The result of elemental analysis for the obtained complex is shown in Table 2-2, and the composition ratio of the complex was obtained. The present complex corresponds to the above composition formula (5).
119-91-5, 119-91-5 2,2′-Biquinoline 8412, acatalyst-ligand compound, is more and more widely used in various fields.
