The free-radical chain addition reaction of dimethyl bromomalonate onto olefins can be easily initiated by electrochemically in situ generated manganic salt used in catalytic amount, to give the 1:1 adduct (dimethyl 2-bromoalkylmalonates) in high chemical and faradaic yield at or near room temperature. The method illustrated here offers an interesting approach to carry out free-radical reactions under very simple reaction conditions.
