Properties of Radical Cations Generated by the Pulse Radiolysis of 1,ω-Bis(diarylethenyl)alkanes. Trapping of Distonic 1,4-Radical Cation by Molecular Dioxygen

Autor: Toshiyuki Tamai, Setsuo Takamuku, Isao Hashida, Yoshio Otsuji, Kazuhiko Mizuno, Akito Ishida

Publikováno v: Chemistry Letters. 23:149-152

Physical and chemical properties of radical cations generated from Ar2C=CH(CH2)nCH=CAr2 (Ar = 4-CH3OC6H4, n = 2–4) were studied by use of pulse radiolysis and γ-radiolysis techniques. When n = 3 and 4, 1,4-radical cations were formed via intramole

Photoinduced Electron-Transfer Reactions of Arylmethyl-Substituted 14 Group Compounds: Photoarylmethylation and Photooxygenation

Autor: Kazuhiko Mizuno, Yoshio Otsuji, Toshiyuki Tamai, Isao Hashida

Publikováno v: Bulletin of the Chemical Society of Japan. 66:3747-3754

Photoreactions of arylmethylsilanes, -germane, and -stannane with 1,4-dicyanonaphthalene (DCN) and 9,10-dicyanoanthracene (DCA) were studied under various conditions. The arylmethylation of DCN and DCA occurred in the photoreaction under nitrogen atm
