Abstract

Reactions of (dimethylamino) phenyloxosulfonium methylide with epoxides were carried out. When aromatic epoxides were used as substrates, cyclopropyl sulfones and oxetanes were obtained. When aliphatic epoxides were used, the products were only the cyclopropyl sulfones. While the aminooxosulfonium ylide acts as a methylene transfer reagent to give the corresponding oxetanes, an intramolecular SN 2 type reaction of the betaines led to ...
