Abstract
The kinetics of oxidation of a typical dipeptide glycylglycine (GG) by bromamine-T have been studied in HClO4 medium at 40-degrees-C. The rate shows first-order dependence on BAT]0 and is fractional order in GG]0 which becomes independent of substrate]0 at higher GG]0 At H+] > 0.02 mol dm-3, the rate is inverse fractional in H+] but is zero order at lower H+] (less-than-or-equal-to 0.02 mol dm-3). Variation in ionic strength or dielectric constant of the medium had no significant effect on the rate. The solvent-isotope effect was measured and k(H2O)'/k(D2O)' = 1.45. Proton inventory studies have been made. The reaction has been studied at different temperatures (308-323 K) and activation parameters have been computed.
