Silica: An efficient catalyst for one-pot regioselective synthesis of dithioethers
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.

Synthesis of α-Halogeno-ω-alkylthioalkanes and α,ω-Bisalkylthioalkanes
The reaction of α,ω-dihalogenated alkanes with alkylthiolates affords α-halogeno-ω-alkylthioalkanes 1 as well as α,ω-bisalkylthioalkanes 2.Products 1 (40 examples) and 2 (22 examples) are easily isolated in good yields by flash chromato
