Abstract

magnified image The novel hydroperoxy sultams, 2,3‐dihydro‐3‐hydroperoxy‐2‐aryl‐4,5‐diphenylisothiazole 1,1‐dioxides, were synthesized by the oxidation of the 2‐aryl‐4,5‐diphenyl substituted isothiazolium salts with H~2~O~2~. These hydroperoxy sultams were investigated as epoxidation agents in the epoxidation reaction of cis‐cyclooctene catalyzed by MoB. 2‐(2‐Chlorophenyl)‐2,3‐dihydro‐3‐hydroperoxy‐4,5‐diphenylisothiazole 1,1‐dioxide was found to have the highest epoxidation ability.
