  • Method for producing 2-halogenated benzoic acids
    Patent number: 10364206
    Abstract: 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.
    Type: Grant

  • METHOD FOR PRODUCING COMPLEX COMPOSED OF ORGANIC NITROGEN COMPOUND AND COPPER (I) SALT OF FLUOROOXO ACID
    Publication number: 20150239911
    Abstract: Disclosed is a method for producing a complex composed of an organic nitrogen compound and a copper (I) salt of a fluorooxo acid with high yield while reducing the corrosion of a reaction vessel. The complex can be produced with high yield while reducing the corrosion of a reaction vessel, by reacting a copper (I) salt, a fluorooxo acid salt and an organic nitrogen compound with one another.
