Electron-Transfer Reactions from Hydroquinone Dianions to 10-Methylacridinium Ion and a Cobalt(III) Porphyrin

Autor: Tomohiro Yorisue, Shunichi Fukuzumi

Publikováno v: Bulletin of the Chemical Society of Japan. 65:715-719

Electron transfer from various hydroquinone dianions (X-Q2−) to 10-methylacridinium ion (AcrH+) and [Co(tpp)]+ (H2tpp = tetraphenylporphyrin) occurs efficiently in deaerated MeCN to yield 10,10′-dimethyl-9,9′-biacridine [(AcrH)2] and [Co(tpp)],

Autocatalytic Reduction of Nitric Acid by an Acid-Stable NADH Analogue

Autor: Shunichi Fukuzumi, Tomohiro Yorisue

Publikováno v: Chemistry Letters. 20:1913-1916

The reduction of nitric acid to nitrous acid by an acid-stable NADH analogue proceeds autocatalytically in the presence of perchloric acid in acetonitrile via novel chain reactions where the reduction of one nitrous acid in the presence of nitric aci

Formation of Proton Gradients in Electron Transport between Two Proton-Conducting Acetonitrile Phases Separated by an Insulating Carbon Disulfide Phase

Autor: Tomohiro Yorisue, Shunichi Fukuzumi

Publikováno v: Chemistry Letters. 20:1835-1838

Proton gradients are formed efficiently, coupled with electron transport from iodide ion to electron acceptors (quinone, nitrite, and dioxygen) between two acetonitrile phases, which are separated by a proton-insulating CS2 phase, by using ferroceniu

10,10′-Dimethyl-9,9′-biacridine acting as a unique electron source compared with the corresponding monomer for the efficient reduction of dioxygen, catalysed by a cobalt porphyrin in the presence of perchloric acid

Autor: Shunichi Fukuzumi, Tomohiro Yorisue

Publikováno v: J. Chem. Soc., Perkin Trans. 2. :1607-1611

An NAD dimer analogue, 10,10′-dimethyl-9,9′-biacridine [(AcrH)2] reduces dioxygen much more efficiently than the corresponding monomer, 10-methyl-9,10-dihydroacridine (AcrH2) in the presence of HClO4 and a catalytic amount of CoTPP+(TPP = tetraph

Acid-Catalyzed One-Electron Reduction of Nitrite to Nitric Oxide by an NADH Analog and 1,1′-Dimethylferrocene in the Absence and Presence of Dioxygen

Autor: Shunichi Fukuzumi, Tomohiro Yorisue

Publikováno v: Chemistry Letters. 19:871-874

One-electron reduction of nitrite to nitric oxide proceeds efficiently by an acid-stable NADH analog, 9,10-dihydro-10-methylacridine (two-electron reductant) as well as 1,1′-dimethylferrocene (one-electron reductant) in the presence of perchloric a
