Reaction Conditions:
with sodium bis(2-methoxyethoxy)aluminium dihydride in toluene at -5 - 5; for 5.5 h;Inert atmosphere;Reagent/catalyst;Solvent;Temperature;
Steps:
1-3 Example 1
bis(3,5-dimethylphenyl) phosphine oxide (0.88g, 3mmol) stir with toluene (2.5mL) to dissolve. Under the protection of argon, red aluminum toluene solution (70%) (0.87g, 3mmol) and toluene (7.5mL) were added dropwiseThe temperature is controlled at -5-0°C, 0.5h is added dropwise, and -5-5°C is reacted for 5h. After the reaction,Add water to quench at a temperature of <5 , let stand for layering, (stand still at -5 for 20min).Toluene layer is desolvated at 0 110 under reduced pressure, pressure is -0.10MPa,The product bis (3,5-dimethylphenyl) phosphine is obtained.The GC purity of the product was 97%, and the yield was 92%.
