Abstract
The electrochemical coupling of dimethyl maleate, methyl cinnamate, 4-phenyl-3-buten-2-one, or methyl acrylate with dibromomethane, 1,3-dibromopropane, 1,4-dibromobutane, or other substituted alkyl dihalides gave satisfactory yields of cyclic products. The reactions were performed in an undivided cell fitted with a sacrificial aluminum anode, in N-methylpyrrolidone (NMP), at constant current, and at room temperature. The role of the anodically generated metallic ions in this cyclocondensation has been evidenced
