    • A method of producing naphthalenedicarboxylic acids by the oxidation of dialkyl-substituted naphthalene with a gas containing molecular oxygen in an organic solvent and in the presence of a catalyst comprising copper and bromine, or a catalyst comprising copper, bromine and at least one kind of element/compound selected from the group of consisting of amine compounds and heavy metallic elements which are vanadium, manganese, iron, nickel, palladium and cerium. And a method of producing diaryldicarboxylic acids by the oxidation of dialkyl-substituted diaryl compounds with a gas containing molecular oxygen in an organic solvent and in the presence of the same catalyst. These methods permit high yields of naphthalenedicarboxylic acids of high purity and of diaryldicarboxylic acids of high purity with the use of small amounts of catalyst.

    • A method for stabilizing an aryl boron compound of formula (1): wherein Ar1, Ar2, and Ar3 are aryl groups, including mixing a compound which has higher affinity for the aryl boron compound than water, as a stabilizer, in a solution or slurry containing the aryl boron compound in a hydrocarbon solvent; and a stabilized composition obtained thereby. The stabilizing method and the stabilized composition of the present invention make it possible to store aryl boron compounds stably over a long term, while keeping their high purity, in the form of forming a substantially homogeneous system in the case of a solution or in the form of forming a substantially homogeneous system by heating in the case of slurry.
