With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13991-08-7,1,2-Bis(diphenylphosphino)benzene,as a common compound, the synthetic route is as follows.
45.6mg mesityl -Cu and 3ml of toluene were added to 48.5mg (0.25mmol) of 7-PyIn and 111.5mg (0.25 mmol) of dppb in a glove box. It forms ayellow solution. It was filtered and coated with a layer of hexane. It formsorange-red crystals. Under UV (356nm), they emit light in a strong orange.Yield: 71%., 13991-08-7
As the paragraph descriping shows that 13991-08-7 is playing an increasingly important role.
