The reaction of dihaloethylenes with acetate anions in the presence of palladium(II) salts gave trans-diacetoxyethylenes catalytically. It was found that the system, PdCl2–NaOAc–CH3CN is the best for the diacetoxylation of dihaloethylenes, and that palladium(II) salts catalyze the isomerization of trans-diacetoxyethylene to its 1,1-diacetoxy derivative. The mechanism was also discussed.
二卤乙烯与醋酸根离子在钯(II)盐存在下的反应催化生成反式二醋酸乙烯。研究发现,PdCl2–NaOAc–CH3CN系统是二卤乙烯二醋酸化的最佳选择,并且钯(II)盐催化反式二醋酸乙烯异构化为其1,1-二醋酸衍生物。文中还讨论了该反应机制。
