(57) [Problem] To provide a method for producing a high-quality, high-yield sulfonyl compound with a small number of steps. SOLUTION: A phenol compound represented by the general formula (2) and a sulfonyl halide compound represented by the general formula (3) are prepared by using the sulfonyl compound represented by the general formula (4) as a solvent in the presence of a Lewis acid catalyst. A method for producing a sulfonyl compound represented by the general formula (1): Embedded image (Wherein, X represents a hydrogen atom or a lower alkyl group, R 1 To R 3 may be the same or different and each represents a hydrogen atom, a halogen atom, a lower alkyl group or a cycloalkyl group, and R 4 represents a lower alkyl group or a tetramethylene group in which R 4 forms a ring) |
