A Novel Synthesis of Dimethyl Malonate by Carbonylation of Methyl Chloroacetate Catalyzed by Cobalt Complex

Department of Chemistry, Zhejiang University, Hangzhou 310027

Received Date: 15 August 2000

A novel method of preparing dimethyl malonate by carbonylation of methyl chloroacetate catalyzed by Na[Co(CO)₄] was proposed. Na[Co(CO)₄] was synthesized in situ in the presence of Na₂S₂O₃ and iron powder. The effects of some reaction parameters such as temperature, CO pressure and the concentrations of catalyst on the yields of dimethyl malonate were discussed. The kinetic data were studied and a possible reaction mechanism was proposed.
