[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 کاملPhotosubstitution Reactions of Aromatic Compounds
In nucleophilic aromatic photosubstitution, just as in aromatic substitution in the ground state, substituents can have directing and activating effects. Four rules, which describe orientation of nucleophilic substitution in the excited state, can now be formulated. They are: (a) meta-activation by the nitro group (b) ortho/para-activation by the methoxy group (and probably also by other electr...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولLiquid-phase Catalytic Transfer Hydrogenation of Aromatic Nitro Compounds over Nickel-doped Carbon Catalysts
Ni-doped carbon aerogel catalysts were prepared through sol-gel polycondensation of furfural with resorcinol in the presence of nickel nitrate salts, followed by drying at ambient pressure and then carbonization in N2. The catalysts were used for catalytic transfer hydrogenation of aromatic nitro compounds with propan-2-ol as hydrogen donor and KOH as promoter, and have been found to exhibit ex...
متن کامل[Formations and reactions of aromatic furazan compounds].
A reaction from various kinds of nitroquinoline with hydroxylamine in potassium hydroxide alkalinity produced a novel product, furazanoquinoline, besides the known amino derivatives. The products obtained were furazano [3,4-f] quinoline (5) from 5-nitroquinoline (1) and 6-nitroquinoline (6), and furazano [3,4-h] quinoline (10) from 7-nitroquinoline (8) and 8-nitroquinoline (11). The reaction me...
