The direct arylation of aliphatic ketones has been developed via Pd-catalyzed β-C(sp3)–H bond functionalization with 2-(aminooxy)-N,N-dimethylacetamide as a novel transient directing group (TDG), which showed remarkable directing ability to generate arylated products in moderate to good yields. Furthermore, the reaction can tolerate abundant substrate of ketones and aryl iodides. This study expands
脂族酮的直接芳基化反应是通过Pd催化的β-C(sp 3)-H键功能化,以2-(氨基氧基)-N,N-二甲基乙酰胺作为新型的瞬态导向基团(TDG),这表明了出色的导向作用产生中等至良好产量的芳基化产品的能力。此外,该反应可以耐受酮和芳基碘的丰富底物。这项研究扩大了TDG的应用范围。
