Dysprosium(III)‐trifluoromethanesulfonate [Dy(OTf) 3 ] is one of the lanthanide triflates [Ln(OTf) 3 ] that is utilized as favorable mild, powerful and selective Lewis acids for a variety of functional group transformations. The cover feature shows Dy(OTf) 3 ‐catalyzed selective S‐deacetylation of functionalized thioesters, including bifunctional organic molecules and carbohydrates (1‐SAc). Notably, Dy(OTf) 3 is stable in aqueous media and can be recovered from the reaction mixture by aqueous extraction and recycled.
