DIMETHYL BROMOMALONATE Usage And Synthesis
Chemical Propertiesclear colorless to light yellow liquid
UsesDimethyl bromomalonate may be used in the enantioselective synthesis of nitrocyclopropanes.
General DescriptionDimethyl bromomalonate undergoes manganese(III)-promoted free-radical chain addition reaction with olefins, to yield dimethyl 2-bromoalkylmalonates. Organocatalyzed Michael addition of dimethyl bromomalonate to nitrostyrenes to yield synthetically useful nitrocyclopropanes has been reported. Dimethyl bromomalonate reacts readily with arylnitroso compounds to yield the corresponding N-aryl-C,C-dimethoxycarbonylnitrones.
