Bubbling SO2F2 gas into a solution of olefin, 30% aqueous hydrogen peroxide, and 2 M aqueous potassium carbonate in 1,4-dioxane at room temperature for 1 h provides the corresponding epoxides in good to excellent yields. This inexpensive, mild, and highly efficient epoxidizing system is suitable to a variety of olefinic substrates including electron-rich and electron-deficient ones.
