Abstract : The reactions of peroxy, radicals with 2,4,6-trit-butyl substituted phenol, aniline, and thiophenol have been examined by a kinetic method. The primary process involves abstraction of the hydrogen atom attached to the functional group, since all three compounds show fairly large isotope effects when this hydrogen is replaced by deuterium. The phenol and aniline react with about two peroxy radicals per molecule. In contrast, the thiophenol reacts with only a single peroxy radical. (Author)
