The purpose of the present invention is to provide a method for producing 2-halogenated benzoic acids, the method imparting high regioselectivity (high selectivity) and having a shorter reaction time than does the conventional reaction. This method for producing 2-halogenated benzoic acids, in order to achieve the above purpose, is characterized in that benzoic acids and a halogenating agent are reacted in the presence of an alkaline compound, making it possible to highly selectively obtain 2-halogenated benzoic acids.
本发明的目的是提供一种生产 2-卤代苯甲酸的方法,该方法具有高区域选择性 (高选择性),并且与传统反应相比,反应时间更短。为了达到上述目的,这种生产 2-卤代苯甲酸的方法的特点是苯甲酸和卤化剂在碱性化合物存在下进行反应,从而可以高选择性地获得 2-卤代苯甲酸。
