A site-selective metal-free dealkylative approach to synthesize aryl alkyl and symmetrical dialkyl sulfides has been developed. This procedure is convenient and has wide functional group tolerance giving rise to sulfides carrying various alkyl chains from simple alkyl sulfides and alkyl halides in good to excellent yields. This transalkylation proceeds by an ionic mechanism via sulfonium intermediates and it was proposed that dimethylacetamide (DMAC) may participate in part to promote the reaction.

Despite the widespread use of transition-metal catalysts in organic synthesis, transition-metal-catalyzed reactions of organosulfur compounds, which are known as catalyst poisons, have been difficult. In particular, the transition-metal-catalyzed addition of organosulfur compounds to unactivated alkenes remains a challenge. A novel gold-catalyzed hydrothiolation of unactivated alkenes is presented, which proceeds effectively to give the anti-Markovnikov-selective adducts in good yields and in a regioselective manner.
Hole transfer promoted hydrogenation: One-electron oxidation as a strategy for selective reduction of π-bonds

One-electron oxidation is developed as a strategy for selective and efficient reduction of relatively ionizable functionalities, including conjugated dienes, styrenes, vinyl sulfides, aromatics, and even strained σ-bonds. Reduction is highly sensitive to substrate ionizability and permits selective reduction of the more ionizable function in a difunctional context. Ionization of the substrates to cation radicals is effected via the mild hole transfer agent tris(4-bromophenyl)aminium hexachloroantimonate, and subsequent reduction of the cation radicals is accomplished by tributyltin hydride. The new reduction conditions provide a novel route for generating free radicals which may prove useful in the field of radical cyclizations. This is especially attractive in the case of phenyl vinyl sulfides since the phenylthio group, which remains intact subsequent to cyclization, provides versatile functionality for further synthetic operations.
