With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13440-07-8,Di(naphthalen-1-yl)phosphine oxide,as a common compound, the synthetic route is as follows.
151 mg (0.5 mmol) of bis(1-naphthyl)phosphorus,115.5 mg (0.75 mmol) of 4,4-dimethoxy-2,5-cyclohexadien-1-one,0.05 mmol of water and 1.0 mL of toluene were placed in a Schlenk tube under nitrogen, and the reaction was stirred at 100 C for 12 hours. After completion of the reaction, it was purified by column chromatography, and the isolated yield was 64%., 13440-07-8
As the paragraph descriping shows that 13440-07-8 is playing an increasingly important role.
