Abstract

Abstract α, β unsaturated alcohols are transformed in 2–5 mn and in 70–90% yield (< 90% pure) into their corresponding iodides when they are allowed to react with solid P2I4 under 10− 2 Torr at 85° C. With unsymmetrical alcohols, an allylic rearrangement always leads to the more stable iodide.
