A novel potassium persulfate (K2S2O8) mediated thiolation of allenylphosphine oxides with diaryl sulfides is disclosed. Mechanistic studies indicate that K2S2O8 homolyzes the diaryl sulfide to produce a thiyl radical (PhS•), which is followed by C–O bond cleavage of the allenylphosphine oxide under metal-free conditions, affording novel S,P-bifunctionalized butadienes in moderate to excellent yields.
