A novel design-based removable N,O-bidentate directing group based on commercially available 4-aminoantipyrine (AAP) is reported. Aromatic benzamides bearing the AAP directing group underwent efficient Ru-catalyzed C(sp2)−H bond arylation reactions under mild reaction conditions and using [RuCl2(PPh3)3] as a catalyst. Various differently substituted and electronically different antipyrinyl (AP) benzamides
报道了一种基于可商购的 4-氨基安替比林 (AAP)的基于设计的新型可移除N , O -双齿导向基团。带有 AAP 导向基团的芳香族苯甲酰胺在温和的反应条件下并使用 [RuCl 2 (PPh 3 ) 3 ] 作为催化剂进行有效的 Ru 催化的 C(sp 2 )-H 键芳基化反应。各种不同取代和电子学上不同的反吡喃基 (AP) 苯甲酰胺参与了 Ru 催化的 C(sp 2 )-H 芳基化反应,并具有良好的产率和良好的官能团耐受性。
