The development of a silica-promoted highly selective synthesis of 1,2 or 1,3-dithioethers via solvent-free one-pot tandem reactions of an allyl bromide with excess thiol at room temperature is described. The choice of silica gel, either pre-calcined or moistened with water, exhibited notable regioselectivity in the formation of dithioethers. Plausible mechanistic routes were explored and postulated.

Bis-sulfinyloxiranes were synthesized in two steps from carbonyl compounds and α,ω-dichloro-α,ω-disulfinylalkanes, which were synthesized from α,ω-dibromoalkanes in three steps, in good yields. Treatment of the bis-sulfinyloxiranes with sodium benzenethiolate and piperidine gave α,α′-di(phenylthio) diketones and α,α′-diamino diketones, respectively, in high yields. From these products, some kinds of diketones were synthesized in good to high yields.

The reactions of a variety of 1,3-bis(phenylthio)propanes with butyllithium have been shown to produce cyclopropyl phenyl sulfides in good to high yields.A new and convenient in situ preparation of 1-lithiocyclopropyl phenyl sulfide can be readily carried out by treating 1,3-bis(phenylthio)propane with 2 equiv. of butyllithium at 0 degC in THF.The reaction with electrophiles proceeds in good yield.O-Aryl and O-alkyl S-cyclopropyl dithiocarbonates also can be prepared in good yields. 1,2-Bis(phenylthio)ethane was converted to phenyl vinyl sulfide on treatment with butyllithium, while 1,4-bis(phenylthio)butane was recovered unchanged by a similar treatment.
