Chapman, D. M.,Buchanan, A. C.,Smith, G. P.,Mamantov, G.
, p. 654 - 663 (1986)
The electrochemical and homogeneous oxidations of phenoxazine (POZ) and phenothiazine (PTZ) to their highly persistent radical cations, POZ+. and PTZ+., and dications, POZ2+ and PTZ2+, were studies in anhydrous

The kinetics of the oxidation of oxovanadium(IV), VO(H2O)52+, by RuL33+ and NiL33+ and the reduction of dioxovanadium(V), VO2(H2O)4+, by OsL33+ (L is 2,2′-bipyridine, 1,10-phenanthroline, or a substituted derivative) were studied in acidic aqueous media at 25°C. The oxidations of VO2+ displayed an inverse rate dependence on acid concentration with a rate law of the form kobsd = ka + kb[H+]-1, while the rate constants for the reduction of VO2+ increased with [H+]; kobsd = kc + kd[H+]. The more reactive vanadium(IV) and -(V) species are the VO(OH)+ and VO(OH)2+ ions, respectively, and an application of the Marcus relationship to the cross-reaction data yields a self-exchange rate constant of ～ 10-3 M-1 s-1 for the VO(OH)+/2+ couple. The exchange rate constant is similar to the corresponding values derived from Marcus calculations for Fe2+/3+(aq) and the isoelectronic TiOH2+/3+(aq) couple.
