    • The reversibility of the addition of sulfanyl radicals to C-C double bonds precludes, for example, the radical addition of disulfides to C-C double bonds, which is inefficient unless either by employing alkynes instead of alkenes (see refs 7a above and 13a below) or in the presence of a very good radical trap such as a diselenide, see:;;;;; J. Org. Chem. 1992, 111 -115 or a very efficient H-donor, see

    • For a kinetic study on the addition of benzene sulfanyl radicals to alkynes, see:;;, where that addition has been suggested to be slightly reversible. It is worth noting that addition of sulfur-centered radicals to alkynes is not always necessarily an irreversible process, provided that the radicals possess additional stabilization with respect to sulfanyls: sulfonyl radicals, for example, have been reported to add reversibly to C-C triple bonds, see
