Title: Synthesis of alkoxy and phenoxy substituted aryl sulfides

Abstract: Provided is a novel process for the synthesis of aryl sulfides substituted with an alkoxy or phenoxy substituent. The process comprises reacting an alkoxy or phenoxy substituted aromatic compound with a sulfur dihalide, preferably sulfur dichloride, in the presence of an alkali metal tetrafluoroborate catalyst, with the amount of said aromatic reactant compound preferably being sufficient to solvate the sulfur dichloride and catalyst sufficiently to allow the reaction to occur.
