Site-selective functionalization of arenes that is complementary to classical aromatic substitution reactions remains a long-standing quest in organic synthesis. Exploiting the generation of halenium ion through oxidative process and the protonation of the nitrogen containing function in HF/SbF5, the chlorination and iodination of classically inert Csp2?H bonds of aromatic amines occurs. Furthermore, the superacid-promoted (poly)protonation of the molecules acts as a protection, favoring the late-stage selective halogenation of natural alkaloids and active pharmaceutical ingredients.
Synthesis of acetamides from aryl amines and acetonitrile by diazotization under metal-free conditions
Duan, Pan,Guo, Yu,Kang, Huan,Li, Yi-Na,Wen, Xianghao,Xiao, Fang,Zeng, Yao-Fu,Zhang, Na-Na
supporting information, p. 2169 - 2172 (2019/11/25)
An efficient and metal-free coupling reaction has been developed that affords acetamides from the corresponding aryl amines and acetonitrile. This method tolerates a wide range of functional groups and is selective toward aryl amines. Preliminary mechanistic studies were conducted.

, p. 1861 - 1864 (2007/10/03)
A novel thioacetate mediated one-step reductive acetamidation of aryl nitro compounds was developed and applied to an efficient synthesis of acetaminophen. The reaction also proceeds well without a solvent in the presence of a catalytic amount of surfactant.

Page/Page column 12; 13, (2008/06/13)
The present invention provides a method for the reductive acetamidation of an aryl nitro compound by reacting a substituted acid with an aryl nitro compound and adding a catalytic amount of a base with the substituted acid and the aryl nitro compound to form an acetamidation aryl nitro compound. The acetamidation aryl nitro compound is then purified.

Pd-catalyzed ortho-selective oxidative coupling of halogenated acetanilides with acrylates
Lee, George T.,Jiang, Xinglong,Prasad, Kapa,Repic, Oljan,Blacklock, Thomas J.
, p. 1921 - 1924 (2007/10/03)
Coupling of different halogenated acetanilides with acrylates using Pd-catalyzed ortho-selective C-H bond activation is reported. The yields of coupled products are low to high depending on the substrate. In general, arenes with electron-rich substituents like methoxy and methyl groups gave higher yields of the coupled products. The presence of the halogen substituent did not interfere with the activation process under these conditions.
