Preparation of Valerophenone
Add 156g benzene, 900mL dichloromethane and 146.5g anhydrous aluminum trichloride into a 2L three-necked flask, cool down to 0-5°C, slowly add 120.5g n-valeryl chloride dropwise, keep the internal temperature 0-10 °C. After the dropwise addition, the temperature was raised to 40 °C, and the reaction was stirred for 2 h. Under ice bath cooling, 500 mL of 1N hydrochloric acid solution was slowly added dropwise, and the solution was separated after the dropwise addition was completed. The aqueous phase was extracted with an additional 400 mL of DCM. After combining the organic phases, concentrate under reduced pressure and distill to obtain 142 g of valerophenone with a yield of 87%.
- Report two
Dissolve 6.3 ml (0.05 mol) of methyl benzoate and 0.05 g of cuprous iodide in anhydrous tetrahydrofuran, and add dropwise 0.05 mol (diethyl ether solution prepared with 1.2 g of magnesium metal and a corresponding amount of n-butane bromide) Alkyl Grignard reagent, titrating Grignard reagent for about half an hour, and then reacting for about three hours to finally obtain 7.8 g of the target product, valerophenone, with a yield of 96%.
