tandem halogenation/semipinacol rearrangement of allyl alcohols with NaX (X = Cl, Br, I) in H2O under open-air conditions has been demonstrated. The catalyst-free process affords various halogenated products in moderate to excellent yields (up to 98%). The features of this procedure include catalyst-free process, aqueous medium, low-cost sodium halide, open-air conditions, excellent yield and gram scalable
