Synthesis of Novel 2,3-Dihydro-3-hydroperoxy-2-aryl-4,5-diphenylisothiazole 1,1-Dioxides and Their Epoxidation Ability

[摘要]：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 H2O2. 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.
