METHOD OF PRODUCTION FOR 2-HALOGENATED BENZOIC ACIDS
PROBLEM TO BE SOLVED: To provide a method of production for 2-halogenated benzoic acids. SOLUTION: 2-Halogenated benzoic acids of formula (I) are produced by reacting benzoic acids of formula (II) with a halogenating agent in the presence of a Pd catalyst. (A is -OH, -OM (M is an alkali metal), -N(R...
