硫代磷酸二乙酯

反应条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: In a round bottomed flask, 4-hydroxybenzonitrile (5.00 g, 41.9 mmol), diethylthiophosphoric acid (7.02 g, 41.9 mmol), and water (8 ml) were heated with stirring to about 80° C. for about thirty minutes. An additional 10 ml of water was then added to the suspension, and the reaction was heated for about another one hour. The mixture was then allowed to stir for about sixteen hours at room temperature and was then extracted with water and 1:1 ether/ethyl acetate. The combined organic extracts were dried over magnesium sulfate, filtered, and concentrated in vacuo. The resulting solid was purified by column chromatography (silica gel; hexanes to ethyl acetate). The product was isolated as a yellow solid (5.54 g, 87% yield). 1H NMR (CD3OD): δ6.74 (d, 2H, J=9.1 Hz), 7.83 (d, 2H, J=8.7 Hz). the reaction was heated for about another one hour to stir for about sixteen hours at room temperature was then extracted with water and 1:1 ether/ethyl acetate The combined organic extracts were dried over magnesium sulfate filtered concentrated in vacuo The resulting solid was purified by column chromatography (silica gel; hexanes to ethyl acetate)
