oxidative C-H allylation of N-acetylbenzamides with 1,3-dienes is described. The presence of allylic hydrogens cis to the less substituted alkene of the 1,3-diene is important for the success of these reactions. With the assistance of reactions using deuterated 1,3-dienes, a proposed mechanism is provided. The key step is postulated to be the first reported examples of allyl-to-allyl 1,4-Rh(III) migration
描述了 Rh(III) 催化的 N-乙酰苯甲酰胺与 1,3-二烯的氧化 CH 烯丙基化。1,3-二烯中较少取代的烯烃顺式烯丙基氢的存在对于这些反应的成功是重要的。在使用氘代 1,3-二烯的反应的帮助下,提供了一种建议的机制。假设关键步骤是首次报道的烯丙基到烯丙基 1,4-Rh(III) 迁移的例子。
