Mechanism and regioselectivity of electrophilic aromatic nitration in solution: the validity of the transition state approach
The potential energy surfaces in gas phase and in aqueous solution for the nitration of benzene, chlorobenzene, and phenol have been elucidated with density functional theory at the M06-2X/6-311G(d,p) level combined with the polarizable continuum solvent model (PCM). Three reaction intermediates have been identified along both surfaces: the unoriented π-complex (I), the oriented reaction comple...
متن کامل6-[4-(Diphenylamino)phenyl]quinoline 1-oxide
In the title mol-ecule, C(27)H(20)N(2)O, a triphenyl-amine derivative of quinoline, the three benzene rings linked through an N atom form a propeller shape, with dihedral angles between the mean planes of pairs of rings of 75.57 (9), 55.68 (9) and 83.66 (9)°. The quinoline ring is essentially planar, with an r.m.s. deviation of the fitted atoms of 0.0155 Å, and forms a dihedral angle of 33.52 (...
متن کاملAspects, mechanism, and biological relevance of mitochondrial protein nitration sustained by mitochondrial nitric oxide synthase.
The goal of this study was to explore the occurrence of nitrated proteins in mitochondria given that these organelles are endowed with a mitochondrial nitric oxide (NO.-) synthase and considering the important role that mitochondria have in energy metabolism. Our hypothesis is that nitration of proteins constitutes a posttranslational modification by which NO.- exhibits long-term effects above ...

متن کاملInvestigations into the Regioselectivity of Fischer Indole and Friedländer Quinoline Syntheses with Octahydroisobenzofuran and Octahydroisoindole Derivatives
A Fischer indole synthesis with a cis-configurated octahydroisobenzofuran-6-one yielded exclusively a furo[3,4-c]carbazole derivative as the product of a regioselective angular annulation reaction. A Friedländer quinoline synthesis from the same substrate gave a mixture of angular and linear annulation products, i. e. furo[3,4-a]acridine and furo[3,4-b]acridine derivatives. When submitting a mi...
