An improved method of preparation of halopropargylalcohol is described. Hydration of halopropargylalcohol followed by hydrolysis gave dihydroxyacetone which was identified as its dibenzoate. 2-Butyne-1,4-diol was converted into acetoxymethyl vinyl ketone. 1,4-Diacetoxy-3-bromobutan-2-one obtained by the addition of acetyl hypobromite to the vinyl ketone was treated with silver acetate to yield t
