Iron(III)-bipyridine complex was prepared andcharacterized by UV-Visible spectrophotometer. Kineticstudy was carried out by using this iron(III)-bipyridinewith thiodipropionic acid in aqueous acetonitrile solution.The reaction was optimized by studying the effect onsubstrate, solvent, oxidant, acidity and temperature. Firstorder, second order rate constants and activationparameters were calculated. The above reaction wasfound to be second order and proceeded through electrontransfer from thiodipropionic acid to iron(III)-bipyridinecomplex. The product was characterized and confirmedby IR and NMR spectroscopy.Keywords: Thiodipropionic acid, Iron(III)-bipyridine complex,kinetic study of Iron(III)-bipyridyl complexes.

Predominant Species

A kinetic study of the electron-transfer reaction between a model azobenzene and dihydrophenazonium ion-radical and dihydrophenazine was carried out in 0.2 N sulfuric acid in 50 v/v aqueous acetonitrile. The second-order rate constant for the dihydrophenazine is greater than that of the ion-radical by a factor of 104. It is shown that in solutions in which the ion-radical is the predominant species, the principal electron-transfer agent is the dihydrophenazine formed by dismutation of the radical.
