variety of P(O)H compounds including H‐phosphonates, H‐phosphinates and diarylphosphine oxides can be used to produce 4‐phosphoryl 2,3‐allenols under mild conditions. The stereoselective synthesis of 1‐phosphoryl 1,3‐butadienes from 4‐phosphoryl 2,3‐allenols and organoboronic acids via a palladium‐catalyzedcoupling reaction is also described.
