The use of palladium to effect two different reactions on a common starting material is presented. With a copper oxidant, an aminohalogenation is achieved to produce oxazolidinones. When the copper is absent, a [3,3]-sigmatropic rearrangement takes place to produce allylic amides.
                                    展示了利用
钯在相同起始材料上进行两种不同反应的应用。使用
铜氧化剂时,实现了
氨基卤化反应,生成氧杂环二酮。当没有
铜时,则发生[3,3]-西格玛重排,生成烯丙基酰胺。
