Oxidative dimerization of lithium ester enoalates is effectively promoted by TiCl4, which serves as a new and efficient synthetic method. Mechanistic study indicates that the reaction proceeds via a radical-like mechanism, but it is not a free radical process.

氧化二聚反应,这一新方法具有高效性。机理研究表明,反应通过类自由基机制进行,但并非自由基过程。
