During the development of a palladium catalyzed C–H activation cross-coupling reaction involving acyl halides, it was noted that palladium(II) acetate catalyzes the acylative cleavage of tetrahydrofuran (used as a solvent) at room temperature to afford the corresponding 4-chlorobutyl ester derivative. After optimization, the reaction was shown to work well with epoxides, oxetane and tetrahydrofuran
在涉及酰基卤的钯催化的C–H活化交叉偶联反应的开发过程中,注意到乙酸钯(II)在室温下催化四氢呋喃(用作溶剂)的酰化裂解,得到相应的4-氯丁基酯衍生物。优化后,显示该反应在环氧化物,氧杂环丁烷和四氢呋喃中反应良好,但在室温下仅与氧烷勉强反应。无环醚在相似条件下无法系统反应,但在100°C的微波反应器中进行了完全转化。
