The data about the rate constants of the hydrogen atom abstraction for the reactions of tertbutylperoxy radicals (t-BuO; ) with aldehydes, ethers, and aliphatic amines are summarized in the present work. The rate constants were measured by using a kinetic EPR-technique with a pulse introduction of the reagents. The problem of the reactivity has been discussed based o n the data about the reaction rate constants, the influence of medium on their values, and the correlation dependence It has been concluded that the complete description of the rractivity of organic compounds, containing heteroatoms. with respect to peroxy radical is possible, if to take into account simultaneously the various parameters, which influence the reactivity, such as, the ionization potential ( I ) . the parameter, characterizing a stereoelectronic effect. and the energy of C-H bond. The latter for the cyclic compounds is determined by Brown's rule of
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
