CuSO4-mediated decarboxylative C–N cross-coupling of aromatic carboxylic acids with amides and anilines
摘要:
CuSO4-mediated decarboxylative C-N cross-coupling of aromatic carboxylic acid with amide has been developed, leading to N-arylamides in modest to excellent yields. Anilines bearing electron-withdrawing substituents could also couple efficiently with aromatic carboxylic acids to give diarylamines in good to excellent yields. (C) 2014 Published by Elsevier Ltd.

Abstract An amide-assisted arene nitration is presented, and both mono- and dinitration of protected anilines could be effected by using NaNO2 and NaNO3 as the mono- and bisnitrating agents, respectively. This divergent synthesis is transition-metal- and acid-free, and features a broad substrate scope, low cost, and ortho–para selectivity. Graphical Abstract
