Abstract:

α‐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 α‐mono and α,α‐dibromo products in excellent yields when water is used as solvent.

Keywords: Alkanones; α‐bromination; α,α‐dibromination; water; zinc bromide; zinc dust
