The disulfidation reactions of alkenes with disulfides were thoroughly investigated in this paper. Using H(2)O or DCE as the solvent, most reactions occurred smoothly to give the corresponding disulfidated products in good to high yields at room temperature within 12 h. (C) 2011 Elsevier Ltd.

in HFIP led to desired products in good to excellent yields (up to 96%). In contrast, other solvents, such as isopropanol and dichloroethane, could not promote the same reaction. This method revealed an example of HFIP-promoted transformations under the mild conditions, which greatly highlighted the unique reactivity of this specialsolvent.
