Abstract
A kinetic and product study of hydrolysis of hydroxamate siderophore, i.e. desferal in aqueous hydrochloric acid media (0.029-2.32 mol dm(-3)) is repo rted. Solvent isotope, salt, organic solvents, and temperature effects have also been probed. A Cox-Yates excess acidity analysis of the observed pseu do-first order rate constants as a function of acidity indicates an A-2 mec hanism.
