coupling involving acylation/alkenylation of aryl iodide is reported. The reaction was carried out with readily available starting materials and gave the ortho-acylated styrene in moderate to good yields. Compared with previous Catellani–Lautens reactions, this reaction is the first example of introducing an acyl group at the ortho position of aryl iodides. The proposed PdIV complex, generated via oxidative
报道了涉及芳基碘化物的酰化/烯基化的新的钯催化的三组分偶联。用容易获得的起始原料进行反应,并以中等至良好的产率得到邻酰化的苯乙烯。与以前的Catellani–Lautens反应相比,该反应是在芳基碘化物邻位引入酰基的第一个例子。通过羧酸酐的氧化加成生成的拟议的Pd IV配合物是该转化的关键中间体。
