Abstract

Yb[N(SiMe₃)₂]₂·2THF was found to desulfurize thiols (RSH) and dibenzyl sulfide. With thiols, the extent of desulfurization was a function of the relative stability of the corresponding radical, R·. Radicals were also involved in the desulfurization of dibenzyl sulfide. A unified mechanism involving a series of one‐electron redox steps leading to the generation of organic radical intermediates has been proposed.
