Some tips on 719-80-2

The synthetic route of 719-80-2 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.719-80-2,Ethoxydiphenylphosphine,as a common compound, the synthetic route is as follows.

719-80-2, Ethyl diphenylphosphinite,0.87 g (0.0038 mol), was added dropwise to asolution of 1.25 g (0.0038 mol) of compound 21a in1 mL of diethyl ether on cooling to -5 to 5C. Themixture was left to stand for 24 h at room temperature,and the solvent and volatile components were removedunder reduced pressure. Yield 1.44 g (76.6%), colorlesscrystals, mp 146-148C (from isooctane). The spectralcharacteristics of samples of 23a synthesized bydifferent methods were identical.

The synthetic route of 719-80-2 has been constantly updated, and we look forward to future research findings.
