Abstract
Reaction of the 2-(phenylthio)cycloalkanones 11–13 with thiophenol and chlorotrimethylsilane afforded the 1,2-bis(phenylthio)cycloalkenes 8–10 together with the corresponding 2,3-isomers 15–17 respectively. Treatment of compounds 7–10 with hydrogen peroxide in acetic acid gave the 1,2-bis(phenylsulfonyl)cycloalkenes 1–4.
