Abstract
A new method for the α,α-dichlorination of β-keto esters using Oxone/aluminum trichloride
mixture in aqueous medium has been developed. This useful process has also been applied
successfully for the dichlorination of 1,3-diketones. The dichlorinated compounds
have been produced in one step, high yields, and short reaction times.
Key words
Oxone - aluminum trichloride - dichlorination - β-dicarbonyl
