Dai, Enrui,Dong, Ying,Dong, Yongrui,Kong, Rui,Liang, Deqiang,Liu, Guangzhang,Ma, Yinhai,Wu, Qiong
, (2020/04/27)
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.

Lan, Tian,Yuan, Xian Xia,Yu, Jiang Hong,Jia, Chao,Wang, Yu Shi,Zhang, Hui Juan,Ma, Zi Feng,Ye, Wei Dong
experimental part, p. 253 - 255 (2012/01/04)
Several 6-aminoquinoline derivatives, which could be used in drug design, have been synthesized. The reaction conditions were comparatively studied, and the p-chloroaniline was used as optimum oxidant in Skraup-Doebner-Von Miller reaction. The nitro group was reduced effectively by SnCl2 with no halo-removed occurred.

Sadovski, Oleg,Beharry, Andrew A.,Zhang, Fuzhong,Woolley, G. Andrew
scheme or table, p. 1484 - 1486 (2009/07/25)
Longer switching wavelengths and good photochemical yields and stabilities of the cis isomers in reducing aqueous environments are achieved by introducing 2,2 -aminoalkyl substituents into 4,4 - diamido-substituted azobenzenes. The products are thus suita
Nitric acid in the presence of P2O5 supported on silica gel - A useful reagent for nitration of aromatic compounds under solvent-free conditions
Hajipour, Abdol Reza,Ruoho, Arnold E.
, p. 8307 - 8310 (2007/10/03)
A variety of aromatic compounds are nitrated to parent nitro aromatic compounds under solvent-free conditions using 65% nitric acid in the presence of P2O5 supported on silica gel is described. This methodology is useful for nitration of activated and deactivated aromatic rings.

Hajipour, Abdol R.,Ruoho, Arnold E.
, p. 221 - 226 (2007/10/03)
The use of benzyltriphenylphosphonium nitrate (PhCH2Ph 3P+NO3-) (BTPPN) as a useful reagent for nitration aromatic compounds in the presence of methanesulfonic anhydride under solvent-free conditions is described. This methodology is useful for nitration of activated aromatic rings.
Ozone-mediated Reaction of Anilides and Phenyl Esters with Nitrogen Dioxide: Enhanced Ortho-reactivity and Mechanistic Implications
Suzuki, Hitomi,Tatsumi, Atsuo,Ishibashi, Taro,Mori, Tadashi
, p. 339 - 344 (2007/10/02)
In the presence of ozone, anilides 1 can be nitrated rapidly with nitrogen dioxide in chloroform at 0 deg C to give a high proportion of ortho-nitro derivatives (ortho:para = 1.2-4.4) in good yields.The phenyl esters 15 can be similarly nitrated on the aromatic ring without significant cleavage of the ester bond, giving a mixture of isomeric nitro derivatives in which the ortho-isomer predominantes (ortho:para = 1.1-1.5).The oridin of the enhanced ortho reactivity is discussed in terms of an electron-transfer process involving the nitrogen trioxide as initial electrophile.
