Electron-transfer Reactions. I. The Application of Derivative Linear-sweep Voltammetry for the Determination of the Rate Constants for Electron Transfer between Two Different Organic Anion Radicals

The kinetic of homogeneous electron-transfer reactions between different anion radicals, A-. and B-. can be conveniently studied by derivative linear-sweep voltammetry under conditions where the dianions, B2-, are rapidly protonated. The method involves measurements of the ratio, R’I(A/B) = I’A/I’B, where I’A and I’B are the maximum values of dI/dt for the reduction of A and B, at different sweep rates for solutions containing both substrates.Working curves have been calculated by digital simulation for the concentration ratios, C0B/C0A = 1, 2, 5 and 10.The approximate kinetic range of the method is given by expression (ii). 104 < k1/(dm3 mol-1 s-1) < 108 (ii) The application of this type of measurement is illustrated by the electron transfer from the anion radicals, A-., of several aromatic compounds to the anion radicals, B-., of azobenzene and 4,4'-dimethylazobenzene.The fit of the experimental data to the working curves is generally excellent for substrates having similar diffusion coefficients.The measured rate constants vary from 2.5x106 dm3 mol-1 s-1, for A = phthalazine and B = azobenzene, to 2.7x104 dm-3 mol-1 s-1, for A = anthracene and B = 4,4'-dimethylazobenzene. We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 253-52-1, and how the biochemistry of the body works.Application In Synthesis of Phthalazine
