The syntheses of nine, new dithioethers of the type RS(CH2)xSR, where x = 2 or 3 and R is an alkyl chain, as well as the known x = 2, R = phenyl or cyclohexyl compounds, are reported. The known dithioethers react with RuCl3·3H2O to form trans-RuCl2(dithioether)2 complexes 1 (R = Ph) and 2 (R = C6H11), whereas from the other dithioethers RuCl2[RS(CH2)xSR]2(μ-Cl)2 complexes have been isolated, where x = 3, and R = Et (complex 3), nPr (complex 4), nBu (complex 5), and R = npentyl (complex 6). The complexes are well characterized, including X-ray structures for complexes 1–4. The interest in these compounds stems from oxidation of the dithioethers to the corresponding disulfoxides and their Ru complexes.
Silica: An efficient catalyst for one-pot regioselective synthesis of dithioethers
Kundu, Samir,Roy, Babli,Basu, Basudeb
, p. 26 - 33 (2014/01/23)
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.
Native silica nanoparticle catalyzed anti-Markovnikov addition of thiols to inactivated alkenes and alkynes: a new route to linear and vinyl thioethers
Banerjee, Subhash,Das, Jayanta,Santra, Swadeshmukul
scheme or table, p. 124 - 127 (2009/04/14)
A new route for the synthesis of linear and vinyl thioethers has been demonstrated using bare silica nanoparticle as catalyst at room temperature under solvent-free conditions. The catalyst can be reused up to six times without loss of catalytic activity.
