comparison 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 اولDirectionality of π-holes in nitro compounds.
A statistical survey of the Cambridge Structural Database reveals that the interaction between the π-holes of nitro groups and electron-rich atoms is somewhat directional. High-level ab initio computations indicate energies up to -6.6 kcal mol(-1).
متن کاملThe Quenching of Pyrochlorophyll Fluorescence by Nitro Compounds
We have examined the quenching of pyrochlorophyll fluorescence by a series of substituted nitrobenzenes in ethanol-pyridine solution and the effect of fluorescence quenching on the quantum yield of sensitized photoreduction of three of the nitro compounds by hydrazobenzene. All nitro compounds examined are at least moderately good quenchers of fluorescence. There is a good correlation between t...
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 کاملDetermination of the Relationship between Impact Sensitivity and Electrostatic Sensitivity of Nitro Energetic Compounds through Multiple Linear Regression Method
In this work the relationship between impact sensitivity and electrostatic sensitivity of energetic nitro compounds is investigated. Also, the most important molecular descriptors which have effect on this correlation are studied. The results are shown that the ratio of number of the oxygen atoms to hydrogen atoms ( nO/nH), the number of amino groups(NH2)have an important roles in the proposed...
