  1. 1.

    The reactions of hydroperoxides with sulfides are accompanied by the formation of free radicals; however, the escape of the latter into the volume is small, comprising 10−4 of the number of the reacted hydroperoxide molecules. A scheme of formation of radicals, analogous to the scheme used for the reaction of hydroperoxides with phosphites, was proposed.

  2. 2.

    The synergistic effect of sulfides is explained by the low escape of radicals into the volume, i.e., by the high effectiveness of sulfides in suppressing degenerate branching.
