概要
- 論文の詳細を見る
Dimethyl methylenesuccinate, dimethyl citraconate, and dimethyl mesaconate mutually rearranged in the presence of triethylamine at room temperature. The rearrangement was found dependent on the polarity of the solvent and the basicity of the amine, and the rate was found to be first-order in both ester and amine. A mechanism has been proposed from a kinetic study.
