A method produces a 2′-trifluoromethyl-substituted aromatic ketone and includes reacting a 2-halogen-substituted benzotrifluoride compound with magnesium metal to convert the compound to a Grignard reagent; and reacting the Grignard reagent with an acid anhydride; and then hydrolyzing the resultant to produce a 2′-trifluoromethyl-substituted aromatic ketone. The method of producing a 2′-trifluoromethyl-substituted aromatic ketone enables 2′-trifluoromethyl-substituted aromatic ketone to be produced without using expensive raw materials by generating a Grignard reagent as an intermediate and reacting this Grignard reagent with an acid anhydride in an efficient productivity. The 2′-trifluoromethyl-substituted aromatic ketone that is produced by the method of producing a 2′-trifluoromethyl-substituted aromatic ketone can be used as fine chemicals, raw materials for pharmaceuticals and agrochemicals, raw materials for resins and plastics, electronics and information related materials, optical materials, and the like.
一种方法生产2'-三氟甲基取代的芳香酮,包括将2-卤代取代的苯三氟甲基化合物与镁金属反应,将该化合物转化为格氏试剂;然后将格氏试剂与酸酐反应;然后水解所得物以产生2'-三氟甲基取代的芳香酮。通过这种生产2'-三氟甲基取代的芳香酮的方法,可以在不使用昂贵原材料的情况下生成格氏试剂作为中间体,并将该格氏试剂与酸酐高效地反应,从而生产2'-三氟甲基取代的芳香酮。通过这种生产2'-三氟甲基取代的芳香酮的方法生产的2'-三氟甲基取代的芳香酮可用作精细化学品、制药和农药的原材料、树脂和塑料的原材料、电子和信息相关材料、光学材料等。
