Iron (III) salts (perchlorate and nitrate nonahydrate) in acetonitrile or acetic anhydride at 0–50°C oxidize the ∝-position of malonic esters efficiently via the corresponding radicals. In the presence of olefins and aromatics, inter- and intramolecular free radical chain or oxidative additions are observed.
