Isomer Ratio in Nitration of Naphthalene

Nitration 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...

Mechanistic evaluation of polychlorinated dibenzo-p-dioxin, dibenzofuran and naphthalene isomer fingerprints in microwave pyrolysis of biomass.

Isomer distribution patterns of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and naphthalenes (PCNs) were investigated in microwave-assisted pyrolysis (MAP) products of woody biomass. The feedstocks included bark and impregnated wood. The results indicated that isomer distributions in MAP are more selective compared to those reported from wood burning and waste incineration....

Protein nitration in cardiovascular diseases.

There is growing evidence that cardiovascular disease is associated with progressive changes in the production of free radicals and radical-derived reactive species. These intermediates react with all major cellular constituents and may serve several physiological and pathophysiological functions. The nitration of protein tyrosine residues has been used as a footprint for in vivo production of ...

Naphthalene plasmids in pseudomonads.

A rapid method beginning with the direct lysis of bacteria in alkaline sodium dodecyl sulfate was used to detect naphthalene plasmids in pseudomonads. The strains NCIB 9816, PG, ATCC 17483, and ATCC 17484, which can grow on naphthalene as the sole source of carbon and energy, were examined. All except ATCC 17483 contained more than one plasmid. ATCC 17483 did not contain any plasmids. The large...
