Intramolecular Catalysis of the Hydrolysis of N-Dimethylaminomaleamic Acid

N-Dimethylaminomaleamic acid decomposes in aqueous solution by intramolecular reaction of the ciscarboxy group with the substituted carbamyl group. The reaction follows pseudo first-order kinetics and shows a dependence on pH. This compound retards plant growth probably because 1,1-dimethylhydrazine and 1,1-dimethylhydrazinium hydrogen maleate are products of its decomposition. Under similar conditions N-dimethylaminosuccinamic acid was stable.
