production method | 1. Tobacco: OR,26. 2. Preparation Method: In the reaction flask equipped with stirrer, ventilation tube, dropping funnel, add palladium chloride 0.53g(3mmol), cuprous chloride 2.97g(30mmol),24ml DMF aqueous solution (7:1), oxygen (bubbling) was introduced with stirring for about 1H. 1-Decene (2)4.2g(30mmol) was slowly added dropwise, and the addition was completed for about 10min. After the addition, oxygen was continued at room temperature. The reactant gradually changed from green to black, and after 15min, it turned green again. After aeration with stirring for 24h, the reaction mixture was poured into 100ml of cold 3mol/L hydrochloric acid and extracted five times with diethyl ether. The ether layers were combined, washed with saturated sodium bicarbonate solution and saturated brine successively, and dried over anhydrous magnesium sulfate. After rotary concentration, fractional distillation was performed under reduced pressure, and fractions of 43-50 ° C./133Pa were collected to obtain 3-3.4g (yield: 65%-73%) of acetodecone (1). [1] |
