Direct and Efficient Preparation of gem-Chloronitro Compounds or Nitro Compounds from gem-Bromonitro Compounds
Amrollah-Madjdabadi, A.,Beugelmans, R.,Lechevallier, A.
, p. 826 - 828 (1986)
Sodiumethanethiolate in methanol is an efficient reducing agent for gem-bromonitro compounds; treatment of the resultant nitronates with a protic acid or with N-chlorosuccinimide gives high yields of the corresponding nitro or gem-chloronitro compounds, respectively.
From azides to nitro compounds in a few seconds using HOF·CH3CN
Rozen, Shlomo,Carmeli, Mira
, p. 8118 - 8119 (2003)
HOF·CH3CN, a very efficient oxygen-transfer agent, was reacted with various azides to form the corresponding nitro compounds in excellent yields and in very short reaction times. The respective nitroso derivatives were found to be intermediates in this reaction. When the azides were reacted with MCPBA or DMDO, no reaction took place, and the starting materials were fully recovered. Copyright
Highly selective co-production of nitrocyclohexane and adipic acid from vapor phase catalytic nitration-oxidation of cyclohexane with NO2
You, Kuiyi,Jian, Jian,Xiao, Haijun,Liu, Pingle,Ai, Qiuhong,Luo, He'An

A simple and efficient approach for highly selectivity co-production of nitrocyclohexane and adipic acid from vapor phase nitration-oxidation of cyclohexane with NO2 at atmospheric pressure has been successfully developed in this work. This finding provides a novel strategy for co-production of nitroalkanes and dicarboxylic acids from vapor phase nitration-oxidation of low-carbon cycloalkanes. This method may be very significant to establish such a synthesis process for aliphatic nitro-compounds and dicarboxylic acids in organic fields.
SELECTIVE C-C BOND HYDROGENATION IN UNSATURATED NITRO COMPOUNDS IN THE PRESENCE OF THE RhCl3-ALIQUAT 336 CATALYST SYSTEM

, p. 1321 - 1322 (1987)
The ion pair formed from aqueous rhodium trichloride and Aliquat 336 catalyzes the selective hydrogenation of olefinic bonds of a variety of unsaturated nitro compounds in a two liquid phase system at 30 deg C.Nitrobenzene gives, under these conditions, a mixture of aniline and nitrocyclohexane.
New Method for the Facile Reduction of α-Nitro Sulfones to Nitroalkanes via an Electron-Transfer-Hydrogen Atom Abstraction Mechanism
Chen, Jian,Tanner, Dennis D.
, p. 3897 - 3900 (1988)
The mechanism for the reduction of several α-nitro sulfones with 1,3-dimethyl-2-phenylbenzimidazoline (DMBI) was investigated.The reduction proceeds by a free-radical chain process where the initiation step and one of the propagation steps involve single electron transfer reactions.The synthetic utility of the reduction was investigated.

Ozone-Mediated Amine Oxidation and Beyond: A Solvent-Free, Flow-Chemistry Approach
Skrotzki, Eric A.,Vandavasi, Jaya Kishore,Newman, Stephen G.

Ozone is a powerful oxidant, most commonly used for oxidation of alkenes to carbonyls. The synthetic utility of other ozone-mediated reactions is hindered by its high reactivity and propensity to overoxidize organic molecules, including most solvents. This challenge can largely be mitigated by adsorbing both substrate and ozone onto silica gel, providing a solvent-free oxidation method. In this manuscript, a flow-based packed bed reactor approach is described that provides exceptional control of reaction temperature and time to achieve improved control and chemoselectivity over this challenging transformation. A powerful method to oxidize primary amines into nitroalkanes is achieved. Examples of pyridine, C-H bond, and arene oxidations are also demonstrated, confirming the system is generalizable to diverse ozone-mediated processes.

Paragraph 0067-0071, (2021/06/13)
The invention relates to a preparation method of cyclohexanone oxime. The method comprises the following steps: carrying out partial oxidation reaction on cyclohexylamine and molecular oxygen under the action of a catalyst to obtain an oxidation reaction product consisting of cyclohexanone oxime, a byproduct and possibly unconverted cyclohexylamine; and then treating the oxidation reaction product in one of the following modes: (i) carrying out hydrogenation amination reaction with H2 and NH3 at the same time or carrying out hydrogenation and amination reaction in sequence under the action of a catalyst without separation or after part or all of water in the oxidation reaction product is separated, and then carrying out separation to obtain cyclohexanone oxime; and (ii) carrying out hydrogenation reaction with H2 under the action of a catalyst without separation or after part or all of water is separated out, and then carrying out separation to obtain the cyclohexanone oxime. The method disclosed by the invention has the characteristics of short process flow, small occupied area and investment, low material consumption and energy consumption (low cost), simplicity and convenience in operation, environment friendliness and the like.
