To provide a method for producing a benzodithiol compound easily in high yield, using inexpensive materials, which is useful as one of various functional materials including organic electronic materials, ultraviolet light absorbers, coloring materials and optical materials and as an intermediate for synthesizing these functional materials.
The method for producing a compound of general formula (IV) includes conducting a reaction between a compound of general formula (III) and an oxidizing agent in the presence of water at 1 eq. or more based on the compound of general formula (III). In general formulas (III) and (IV), R1 and R2 are each independently H, alkyl, aryl or a heterocyclic group, wherein the R1 and R2 may be the same as or different from each other or may be bound to each other to form a ring; R3 and R4 are each independently H, alkyl, aryl or a heterocyclic group, wherein the R3 and R4 may be the same as or different from each other or may be bound to each other to form a ring.
