    Abstract: PROBLEM TO BE SOLVED: To provide a method etc., capable of producing a new (substituted thio)dibenzoquinone compound in a high yield and a high regioselectivity by an even industrially simple and suitable method utilizing an aryl-aryl coupling reaction. SOLUTION: This method for producing the (substituted thio)dibenzoquinone compound is characterized by comprising a first process of reacting a (substituted thio)dioxybenzene compound with the (substituted thio)dioxybenzene compound in the presence of a coupling agent to obtain a (substituted thio)tetraoxybiaryl compound, a second process of reacting the (substituted thio)tetraoxybiaryl compound with a hydroxylation agent to obtain a (substituted thio)tetrahydroxybiaryl compound, and a third process of reacting the (substituted thio)tetrahydroxybiaryl compound with an oxidizing agent to obtain the (substituted thio)dibenzoquinone compound.
