With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.50777-76-9,2-(Diphenylphosphino)benzaldehyde,as a common compound, the synthetic route is as follows.
50777-76-9, General procedure: To a dichloromethane solution (15 mL) of 2-diphenylphosphinobenzaldehyde (ca. 3 mmol) was added an equimolar amount of the appropriate substituted amine. An excess of magnesium sulphate was also added to the reaction mixture to remove the water by-product. The reaction was left to stir at room temperature for 16 h, after which time the magnesium sulphate was filtered off and the solvent removed from the filtrate in vacuo to give a yellowe orange oil. The oily crude products of ligands 1a-1f were solidified by dissolving the oil in hot hexane, followed by quick hot filtration of the liquid product. The resultant solution was then cooled at -16 ¡ãC overnight to give an off-white powder, which was filtered and dried in vacuo.
As the paragraph descriping shows that 50777-76-9 is playing an increasingly important role.
