Swavey,Gould
, p. 2159 - 2160 (2007/10/03)
Solutions 0.2 mol dm-3 in Ga1, prepared by dissolving Ga2Cl4 in dry acetonitrile, are stable for more than seven days and may be diluted 300- to 1000-fold with O2-free water to give Ga(I) preparations
Mechanism and Mathematical Model of the Oscillating Bromate-Ferroin-Bromomalonic Acid Reaction
Rovinsky, A. B.,Zhabotinsky, A. M.
, p. 6081 - 6084 (2007/10/02)
A mechanism for the oscillatory reaction of the ferroin-catalyzed bromomalonic acid oxidation by bromate is proposed.The mechanism involves eleven steps.The corresponding mathematical model is reduced to a second-order system of differential equations.The model obtained is in good agreement with experiment.

The cyclic voltammogram of a CH3CN solution of + exhibits three anodic current peaks which correspond to the oxidations of the monomer, the dimer, and the trimer, with no cathodic wave on the reverse scan.The anodic peak potentials Epox in such irreversible cyclic voltammograms were determined for various Rh(I) monomers and the oligomers such as +, 2+, 2+, 2+, 3+, and 4+ (R=p-MeOC6H4 and Ph, etc; dppm=bis(diphenylphosphino)methane, dicp=1,3-diisocyanopropane).The anodic peak potentials Epox vary mainly with the degree of oligomerization of the Rh(I) complexes, decreasing in the order monomer > dimer > trimer > tetramer, in parallel with the energies of the highest occupied molecular orbitals EHOMO.It has been found that the Epox values are linearly correlated with logarithm of the rate constants for the electron transfer reactions with inorganic oxidants such as 3+ and 3+ (bpy=2,2'-bipyridine) in the context of the Marcus theory as expected when the standard oxidation potentials E0ox would be used.It is thus suggested that the anodic peak potentials of the Rh(I) complexes in the irreversible system can be used as the standard oxidation potentials as far as the relative values are concerned.
