Oxidations of glycine, valine, leucine, alanine and phenylalanine by the title reagent have been performed near their isoelectric pH, at 35 °C. The rate law is-d log[BAB]/dt=k′[Amino acid]x where x is 0.40–0.75. The influence of halide ions, ionic strength, benzene sulfonamide and the dielectric constant of the medium have been studied. Activation parameters have been computed. The rate of oxidation increases in the order: Alanine>phenylalanine>leucine>valine>glycine.Abstract…

Kinetics of oxidation of glycylglycine by bromamine-T in acid medium
AbstractThe kinetics of oxidation of a typical dipeptide glycylglycine (GG) by bromamine-T have been studied in HClO4 medium at 40°C. The rate shows first-order dependence on [BAT]0 and is fractional

The pyrolysis of the boranes is a topic of continuing interest. Lipscomb et al. (1) have published calculations that cast doubt on the long-held view that in the pyrolysis of diborane the
