[Problem]

To provide an industrially preferred method for producing a sulfoxide derivative.

[Solution]

A method for producing a sulfoxide derivative represented by general formula (1),

##STR00001##

the method being characterized in that a sulfide derivative represented by general formula (2)

##STR00002##

is reacted with an oxidizing agent in the presence of a catalyst that is a metal-ligand complex containing a metal compound and, as a ligand, a compound represented by general formula (3),

##STR00003##

and in the presence of a benzoic acid compound represented by general formula (4).

##STR00004##

Benzotriazole phenols with substituents either ortho to the phenol hydroxyl group and/or para to the phenol hydroxyl group can be prepared from the unsubstituted benzotriazole phenol by coupling reactions. The ortho substituent group can be a simple alkoxy or amino group, or the ortho substituent group can be a linking group, linking the benzotriazole phenol to another benzotriazole phenol group.
