Zusammenfassung:	PURPOSE: To directly produce bls(4-chlorophenyl) sulfide useful as an intermediate, etc., for polysulfones, etc., which are engineering plastics from monochlorobenzene and sulfur chlorides. CONSTITUTION: Monochlorobenzene is reacted with sulfur chlorides (sulfur chloride, etc.) by using the monochlorobenzene as a solvent and an iron-based catalyst (iron powder, etc.) as a catalyst to thereby afford bls(4-chlorophenyl) sulfide. Furthermore, the reaction is carried out by using the iron-based catalyst in a molar amount of 0.00001-0.1 based on the monochlorobenzene used and the sulfur chlorides in a molar amount of 0.0001-0.5 based on the monochlorobenzene used at 0-150 deg.C reactional temperature.
