Nitric Acid Decomposition Kinetics in Mixed Acid and their Use in the Modelling of Aromatic Nitration
Nitric acid decomposition in mixed acid (an aqueous mixture of nitric and sulfuric acids) was studied from a chemical and a kinetic point of view. The study was focused on the behavior of the reactive mixture in an open system in which the gas formed through the decomposition process can leave the vessel. The reaction network, through which the system could develop, depending on the chemical co...
متن کاملNitration of naphthalene and remarks on the mechanism of electrophilic aromatic nitration.
Naphthalene was nitrated with a variety of nitrating agents. Comparison of data with Perrin's electrochemical nitration [Perrin, C. L. (1977) J. Am. Chem. Soc. 99, 5516-5518] shows that nitration of naphthalene gives an alpha-nitronaphthalene to beta-nitronaphthalene ratio that varies between 9 and 29 and is thus not constant. Perrin's data, therefore, are considered to be inconclusive evidence...
متن کاملMelamine trisulfonic acid catalyzed regioselective nitration of aromatic compounds under solvent-free conditions
A simple, mild and efficient method for the regioselective nitration of various aromatic compounds usingpoly(4-vinylpyridinium nitrate) (P4VPyN) in the presence of melamine trisulfonic acid (MTSA), is reported.This method provides several advantages such as good selectiveity between ortho and para positions ofaromatic compounds, clean procedure, simple work-up, short reaction times, solvent-fre...
متن کاملDirect oxidative nitration of aromatic sulfonamides under mild conditions.
A direct nitration of aromatic sulfonamides using sodium nitrite as the nitrating agent has been developed. The reaction shows typically mono-substitution selectivity and can be enlarged to the gram scale with good yield.
متن کاملChemoselective nitration of aromatic sulfonamides with tert-butyl nitrite.
A methodology for the efficient conversion of aromatic sulfonamides into their mono-nitro derivatives using tert-butyl nitrite is reported. The reaction exhibits a high degree of chemoselectivity for sulfonamide functionalized aryl systems, even in the presence of other sensitive or potentially reactive functionalities.
