A variety of ethyl aryl sulfides (1) react with benzyne, with evolution of ethylene, to give phenyl aryl sulfides (3) in excellent yields, thus providing a general synthesis of 3 from arenethiols since 1 are quantitatively obtainable from arenethiols and ethyl bromide.

A mild and improved method for the synthesis of thioethers has been developed. In the presence of cesium carbonate, tetrabutylammonium iodide, and DMF, various alkyl and aryl thiols underwent S-alkylation to afford structurally diverse sulfides in high yield. Unprotected mercaptoalcohols and thioamines reacted chemoselectively at the sulfur moiety exclusively. An example of a one-pot, solid-phase synthesis of a thioether is also described.
