摘要：

alpha-Bromination of alkanones with bromine catalyzed by in situ - generated zinc bromide from zinc dust and bromine in water is investigated. Bromination with dioxane-dibromide as a source of bromine does not require zinc dust and provides selectively alpha-mono and alpha,alpha-dibromo products in excellent yields when water is used as solvent.
