A new deoxygenative thioether formation from carbonyl compounds as well as epoxides is presented (eq. 1–3). The reaction proceeds with the combined use of alkyl or aryl disulfide and tributylphosphine under neutral and mild conditions. The reaction with aldehydes proceeds with special ease to give thioacetals in high yields, and can be a valuable synthetic reaction.
