| Abstract: | The reaction of polybromobenzyl bromides RC6Br4CH2Br (R = Br, OCH3) with diethyl malonate sodium salt in ethanol and dimethylformamide leads to formation of diethyl 2-(polybromobenzyl)malonates, whereas in aqueous ethanol ethyl polybromobenzyl malonates are formed. The same polybromobenzyl bromides react with an equimolar amount of ethyl acetoacetate sodium salt or acetylacetone sodium salt to give C-alkylation products; with excess sodium enolates ethyl 3-(polybromophenyl)propionates and 4-(polybromophenyl)-2-butanones are formed, respectively. |
