Diethyl dibromomalonate and ethyl 2,2-dichloroacetoacetate are effectively reduced with the system pentacarbonyliron-proton-donor compound (water or butyl methyl ketone) to give the corresponding hydrodehalogenation products. These results provide a support for the previous assumption that the key reaction stage is reduction with pentacarbonyliron of initially formed radical to anion which is then involved in proton transfer.
