Rh(III)-Catalyzed ortho-C–H amidation of ketones and aldehydes under cooperative metal organocatalysis has been utilized for synthesizing various ortho-amidocarbonyl analogs, and the reaction for the aldehyde proceeds at ambient temperature. The aniline derivative 3,5-bis(trifluoromethyl)aniline promotes the amidation reaction via a transient imine directing group. The efficient amidation agent is
在协同金属有机催化下,Rh(III)催化的酮和醛的邻位C-H酰胺化反应已被用于合成各种邻位-氨基羰基类似物,并且醛的反应在环境温度下进行。苯胺衍生物3,5-双(三氟甲基)苯胺通过一个瞬时的亚胺导向基团促进酰胺化反应。有效的酰胺化剂是二恶唑酮。在喹啉酮生物碱的合成中已证明了该合成效用。
