## Abstract Tetrasubstituted epoxides, and especially electron‐depleted ones, generally are difficult to prepare. HOF·CH~3~CN complex, probably the best oxygen transfer agent known today, epoxidizes tetrasubstituted alkenes at 0 °C in a matter of minutes or less in excellent yields. HOF·CH~3~CN com
## Abstract In the presence of HOF·CH~3~CN, a wide range of thienopyrroles can be transformed efficiently into the corresponding S,S‐dioxides at 25 °C.
