A palladium-catalyzed ortho-C-H amidation of anilides by N-nosyloxycarbamates was developed for the synthesis of 2-aminoanilines. This reaction can be carried out under relatively mild conditions and exhibits excellent regioselectivity and functional group tolerance. The amidation reaction is probably initiated by rate-limiting C-H cyclopalladation (k(H)/k(D) = 3.7) to form an arylpalladium complex, followed by nitrene functionalization.
钯催化的 N-硝酰氧基氨基甲酸酯对酰苯胺的邻位 C-H 酰胺化反应被开发用于合成 2-氨基苯胺。该反应可以在相对温和的条件下进行，并表现出优异的区域选择性和官能团耐受性。酰胺化反应可能是通过限速的 C-H 环钯化（k(H)/k(D) = 3.7）引发的，形成芳基钯配合物，然后进行氮宾官能化。
