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.

Abstract Metal triflate–catalyzed Se-Se bond cleavage would generate selenyl cations, which could add to activated C=C double bond selectively. The reaction conditions were mild and could be easily handled. The cleavage of Se-Se bond in this novel way undermildconditions might expand the view of organic synthesis and facilitate new synthetic strategies.
