A K2S2O8/I-2 promoted C-S coupling reaction of beta-diketones with disulfides has been described. The resulting alpha-thio-beta-diketone compounds were obtained in good to excellent yields. Both diaryl and dialkyl disulfides coupled well with a variety of beta-diketones under transition metal-free and solvent-free conditions.
