2-Bromomaleic acid

2-Bromomaleic acid

The title compound, C4H3BrO4, was obtained from a solution of meso-2,3-dibromosuccinic acid and vanadium(IV) oxide. The crystals are isostructural with chloromaleic acid and the molecule has two geometrically different carboxyl groups, one of which has delocalized C—O bonds and is esse...
