719-80-2, Ethoxydiphenylphosphine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
719-80-2, A mixed solution of Compound 558-4 (10.0 g, 0.023 mol), nickel(II) chloride (1.79 g, 0.0138 mol), and benzonitrile was heated to 180 C. and stirred for 1 hour in a two neck round bottom flask (two neck r.b.f) under nitrogen. Ph2POEt (ethyl diphenylphosphinite) (8.48 g, 0.0368 mol) was slowly added dropwise to the above mixture and then stirred for 2 hours. The reaction mixture cooled to room temperature was extracted with MC (methylene chloride)/H2O and dried using MgSO4 and then filtered. After being concentrated, the resultant reaction product was separated by column chromatography (SiO2, hexane_MC=2:1). As a result, a white solid compound 571 (6.4 g, 58%) was obtained.
The synthetic route of 719-80-2 has been constantly updated, and we look forward to future research findings.
