Comparison of spin density calculation methods for various alkyl-substituted 9,10-anthraquinone anion radicals in the solution phase

Eloranta, Jussi,Vatanen, Virpi,Groenroos, Antti,Vuolle, Mikko,Maekelae, Reijo,Heikkilae, Hilkka

, p. 898 - 902 (1996)

EPR and ENDOR spectra were recorded for 2-methyl-9,10-anthraquinone (2-methylAQ), 2-ethylAQ, 2-tertbutylAQ and 2,3-dimethylAQ anion radicals in the solution phase. The EPR spectra were simulated with the help of ENDOR data. The experimental isotropic hyperfine coupling constants (IHFCs) were compared with calculated values from semi-empirical INDO, spin-restricted AM1/CI and B3PW91 density-functional methods. The best computational methods for the IHFCs were the semi-empirical AM1/CI method and the B3PW91 density-functional method with a large basis set.

Binuclear iron(III) octakis(perfluorophenyl)tetraazaporphyrin μ-oxodimer: A highly efficient catalyst for biomimetic oxygenation reactions

Yusubov, Mekhman S.,Celik, Cumali,Geraskina, Margarita R.,Yoshimura, Akira,Zhdankin, Viktor V.,Nemykin, Victor N.

supporting information, p. 5687 - 5690 (2014/12/11)

Binuclear iron(III) octakis(perfluorophenyl)tetraazaporphyrin μ-oxodimer complex was prepared by the reaction of bis(perfluorophenyl)maleonitrile and Fe(CO)5and tested in catalytic oxygenation reactions of several hydrocarbons in comparison with the analogous non-fluorinated phthalocyanine complexes. Results of the study demonstrate that this complex is a highly efficient catalyst for the oxygenation of anthracene, 2-tert-butylanthracene, naphthalene, 2-methylnaphthalene, phenanthrene, adamantane, and toluene using iodosylbenzene, oligomeric iodosylbenzene sulfate, or Oxone as stoichiometric oxidants.

Metalloporphyrin/Iodine(III)-Cocatalyzed oxygenation of aromatic hydrocarbons asc.wiley-vch.de

Yoshimura, Akira,Neu, Heather M.,Nemykin, Victor N.,Zhdankin, Viktor V.

experimental part, p. 1455 - 1460 (2010/08/20)

Hypervalent iodine species have a pronounced catalytic effect on the metalloporphyrinmediated oxygenations of aromatic hydrocarbons. In particular, the oxidation of anthracene to anthraquinone with Oxone readily occurs at room temperature in aqueous acetonitrile in the presence of 5-20 mol% of iodobenzene and 5 mol% of a water-soluble iron(III)-porphyrin complex. 2-tert-Butylan- thracene and phenanthrene also can be oxygenated under similar conditions in the presence of 50 mol% of iodobenzene. The oxidation of styrene in the presence of 20 mol% of iodobenzene leads to a mixture of products of epoxidation and cleavage of the double bond. Partially hydrogenated aromatic hydrocarbons (e.g., 9,10-dihydroanthracene, 1,2,3,4-tetrahydronaphthalene, and 2,3-dihydro-1H- indene) afford under these conditions products of oxidation at the benzylic position in moderate yields. The proposed mechanism for these catalytic oxidations includes two catalytic redox cycles: 1) initial oxidation of iodobenzene with Oxone producing the hydroxy(phenyl)iodonium ion and hydrated iodosylbenzene, and 2) the oxidation of iron(III)-porphyrin to the oxoiron(IV)-porphyrin cation-radical complex by the intermediate iodine(III) species. The oxoiron(IV)-porphyrin cation-radical complex acts as the actual oxygenating agent toward aromatic hydrocarbons.

Binuclear iron(III) phthalocyanine(μ-oxodimer)/tetrabutylammonium oxone: A powerful catalytic system for oxidation of hydrocarbons in organic solution

Neu, Heather M.,Zhdankin, Viktor V.,Nemykin, Victor N.

scheme or table, p. 6545 - 6548 (2011/02/22)

Binuclear iron(III) phthalocyanine-(μ-oxodimer) complex was tested in catalytic oxygenation reactions of several hydrocarbons using tetrabutylammonium oxone as the oxidant in dichloromethane solution at room temperature. Results of the study demonstrate that this is an extremely powerful catalytic system for oxidative conversion of aromatic hydrocarbons (anthracene, 2-tert- butylanthracene, 2-methylnaphthalene, 9, 10-dihydroanthracene, 1,2,3,4-tetrahydronaphthalene, indane, ethylbenzene, toluene, and benzene) to the respective p-quinones in high yields in 5-30 min. Under these conditions, adamantane is oxidized with 71% conversion after 10 min affording a mixture of 1 -adamantanol, 2-adamantanone, 1-hydroxy-2-adamantanone, and 4-protoadamantanone.

Binuclear iron(III) phthalocyanine(μ-oxodimer)-catalyzed oxygenation of aromatic hydrocarbons with iodosylbenzene sulfate and iodosylbenzene as the oxidants

Neu, Heather M.,Yusubov, Mekhman S.,Zhdankin, Viktor V.,Nemykin, Victor N.

scheme or table, p. 3168 - 3174 (2010/04/28)

Two binuclear iron(III) phthalocyanine-(μ-oxodimer) complexes were tested in catalytic oxygenation reactions of several aromatic hydrocarbons using iodosylbenzene (PhIO)n or oligomeric iodosylbenzene sulfate [(PhIO)3SO3]n as the oxidants. Results of this study demonstrate that [(PhIO)3SO3]n is the most reactive oxygenating reagent that can be used as a safe and convenient alternative to the thermally unstable and potentially explosive iodosylbenzene. The pyridine-containing binuclear μ-oxobis-{iron(III)-pyridino[3,4]-9(10), 16(17),23(24)-tri-tertbutyltribenzoporphyrazine} is significantly more active as compared to the traditional μ-oxobis[iron-(III)-2,9(10),16(17),23(24)-tetra- tert-butylphthalocyanine].
