DIMETHYL BROMOMALONATE Usage And Synthesis

Chemical Properties

clear colorless to light yellow liquid

Uses

Dimethyl bromomalonate may be used in the enantioselective synthesis of nitrocyclopropanes.

General Description

Dimethyl 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.
