A three-component reaction of beta-ketosulfone, formaldehyde, and thiol or thiophenol was developed. The reaction was performed in pure water under a catalyst-free condition, and the corresponding Mannich-type thioethers were obtained in good to excellent yields. Finally, a one-pot stepwise four-component reaction of sodium benzenesulfinate, alpha-bromoketone, beta-ketosulfone, and thiophenol was also developed.
