One-pot efficient reductive acetylation of aromatic nitro compounds
An efficient one-pot reductive acetylation of aromatic nitro compounds is developed without isolating the intermediate amine. The nitro compound is efficiently reduced by sodium borohydride and catalytic amount of Pd-C in MeOH-water media in presence / absence of alkali, and the amine thus generated is acetylated by acetic anhydride in situ in excellent yields through easy work-up. The techniqu...
متن کاملBiotransformation of Nitro Aromatic Compounds by Flavin-Free NADH-Azoreductase
Nitro aromatic compounds are the potential toxic organic pollutant released into the environment and are often resistant to degradation under normal environmental conditions. The biotransformation and/or detoxification of these compounds can be possible by microbial azoreductase enzyme. Azoreductase enzyme has an ability to reduce the toxic nitro group to corresponding amino group. In present r...
متن کامل[Reduction of aromatic nitro compounds in the intestine].
An ortho-nitrophenol solution was injected into the intestine which had been removed from an anesthetized mouse by placing a ligature at the duodenum and at the rectum. The intestine was then incubated in Ringer's solution at 37•Ž and the ortho-nitrophenol was found to be reduced to ortho aminophenol. At the same time, it was found that ortho-nitrophenol which was incubated with the intestinal ...
متن کاملDecomposition mechanisms of trinitroalkyl compounds: a theoretical study from aliphatic to aromatic nitro compounds.
The chemical mechanisms involved in the decomposition of trinitroethyl compounds were studied for both aliphatic and aromatic derivatives using density functional theory calculations. At first, in the case of 1,1,1-trinitrobutane, used as a reference molecule, two primary channels were highlighted among the five investigated ones: the breaking of the C-N bond and the HONO elimination. Then, the...
متن کاملThe nature of the mutagenicity and carcinogenicity of nitrated, aromatic compounds in the environment.
Gaseous substances such as nitrogen dioxide (NO2) and sulfur dioxide (SO2) stimulate the process of nitration of polycyclic aromatic hydrocarbons, and the transformation products display a broad spectrum of mutagenicity, genotoxicity, and carcinogenicity. Bacterial mutation by nitroarenes is specific. Tetracyclic nitroarenes are thought to be the most mutagenic compounds in the Salmonella test ...
