The effect of pressure on the oxidation of hydroarenes 3-9 with 2,3-dichloro-5,6-dicyano-1,4-quinone (DDQ; 1 a) or o-chloranil (10), leading to the corresponding arenes, has been investigated. The activation volumes were determined from the pressure dependence of the rate constants of

The journal of physical chemistry. B, 113(23), 8080-8085 (2009-05-21)
The electrochemical reduction of o-chloranil (OCA) in aqueous solution has been studied experimentally and theoretically. The effects of temperature and pH on various thermodynamic parameters were studied by means of cyclic voltammetry. The pH dependence of the redox activity of

This is the first report of UV-Vis spectral investigations of electron donor-acceptor complexes of bio active 3-Nitroso-2-phenylbenzo[d]imidazo[2,1-b]thiazole (BIT1) with chloranils, nitrobenzenes and fullerenes in DMSO medium. Well defined charge transfer (CT) absorption bands in the visible region have been sited.
