Abstract
The present status of sulphenes (R′R″C:SO2) as stable entities or chemical intermediates is discussed. The early report by Locher and Fierz (Helv. Chim. Acta, 10, 642 (1927)) of the preparation of a stable crystalline sulphene has been investigated; it is concluded that their claim is unfounded.The irradiation of unsaturated sultones in the presence of methanol is shown to give sulphonic esters: the corresponding thermal reaction of sultones is known to lead to sulphonic acid derivatives. It is proposed that the irradiation of unsaturated sultones yields sulphenes, which then react with the medium.Keywords
