Yield:1795-31-9 0.13 mol
Reaction Conditions:
with phosphorous acid in tetrahydrofuran at 70; for 4 h;
Steps:
2
Weigh 0.05mol phosphorous acid,Adding 0.15mol of 3-trimethylsilylpyrrolidone,THF is dissolved,Reaction was performed at 70 ° C for 4h.Filtered to give pyrrolidone as a solid,Wash three times with 30ml of petroleum ether,Combined petroleum ether phases,Remove the solvent,GC-MS test.9g was distilled under reduced pressure,Colorless transparent liquid.After adding sodium metal,The reaction was protected under nitrogen at 140 -150 for 20h under anhydrous conditions.After cooling, distilled under reduced pressure,Tris (trimethylsilyl) phosphite was obtained in an amount of 0.13 mol (20 mmHg, 75 ° C).
