Use | Bis [2-(diphenylphosphino) phenyl] ether is used as a chelating ligand in a variety of inorganic reactions, one of which is Copper (I) preparation of dimethyldipyrimidine phosphino phenyl ether complexes. Bis (2-diphenylphosphophenyl) ether is a ligand for the ruthenium-catalyzed synthesis of green amines (amines and alcohols are synthesized by hydrogen reaction). Catalyst Phosphine ligands rely on hydrogen and ruthenium catalysis to synthesize greener amines from amines and alcohols. |
Preparation | Bis (2-diphenylphosphophenyl) ether can be prepared by one-step reaction of diphenyl ether and diphenylphosphine chloride. (1) dilute diphenyl ether (0.02mol) in hexane (50mL), add n-BuLi(42mmol) hexane solution dropwise (added within 5min) at -78 ℃, react for 1h, then rise to room temperature (about 25 ℃), and continue stirring for 16h; (2) then add 15mL of n-hexane solution of diphenylphosphine chloride (42mmol) dropwise to the reaction system of step (1) in an ice water bath (after adding it within about 5min), and then continue to stir and react at room temperature (about 25 ℃) for 16h; Remove the solvent by rotary evaporation to obtain light yellow viscous oil, wash with acetone and vacuum dry to obtain 9.4g white powder, that is, bis (2-diphenylphosphophenyl) ether: the yield is 87%,1H NMR(400MHz,C6D6)δ:7.41-7.26(m,8H,o-PPh2),7.08-6.93(m,14H,m-PPh2,p-PPh2,phenylate),6.91-6.87(t,J = 8Hz,2H,phenylate),6.72-6.66(m,4H,phenylate)ppm. |
