We have demonstrated that hypochlorite (HOCI/OCl-) and hypobromite (HOBr/OBr-) can react with tert-butyl hydroperoxide with close rate constants (k(HOCl) = 10,8 M(-1) x s(1); k(HOBr) = 8,9 M(-1) x (s(-1)). By means of the spin trap 4-pyridyl-1-oxide-N-tert-butyl nitron we have found that both reactions proceed through decomposition of tert-butyl hydroperoxide and generation of tert-butyl peroxyl (OOC(CH3)3) and tert-butoxyl (OC(CH3)3) radicals, the ratio of their the concentrations being dependent on the concentration of tert-butyl hydroperoxide. Thus, hypobromite, similar to hypochlorite, is a precursor of free radicals produced in the reaction with organic hydroperoxides. This reaction can be of great importance in the intensification of free radical processes, namely, in lipid peroxidation at the stage of chain branching.
