Abstract A series of β-bromoketones and β-chloroketones were synthesized by the addition reactions of α, β-unsaturated ketones under BX 3 (X= Br, Cl) and ethylene glycol reaction system. The α, β-unsaturated ester also was successfully converted to its corresponding β- bromoester under the reaction condition.
