An alkyl aryl sulfide of Chemical Formula (III) is prepared by substituting an aryl halogen compound of Chemical Formula (I) with an alkyl lithium organometallic reagent. The sulfide is subsequently reacted with a compound of Chemical Formula (II). Alternatively an aryl halogen compound of Chemical Formula (I) is reacted with Grignard reagent to protect the hydrogen-donating substituent, and then reacted with an alkyl lithium organometallic reagent, and subsequently with sulfur and a compound of Chemical Formula (II). An alkyl aryl sulfide of Chemical Formula (III) is prepared via a one-step reaction without separation or purification of an intermediate compound from various aryl halogen compounds.

one-pot synthetic method for the formation of alkylaryl sulfides from various alkyl halides and lithium aryl thiolates that are prepared in situ by direct halogen−lithium exchange is reported. In particular, the method overcomes many of the problems encountered in previous reports; it is very quick, catalyst-free, and does not involve use of unstable aryl thiols.
