1‐Methoxy‐1‐(phenylthio)cyclopropanes from Olefins via the Pummerer Rearrangement.

Abstract The Pummerer rearrangements of cyclopropyl(methoxy)phenylsulfonium salts proceed via sulfur-stabilized carbocations to yield the title compounds. The sulfonium salts were prepared in high yields from olefins via carbene addition, oxidation, and methylation.
