Sulphonyl-stabilised sulphonium ylids
Abstract
1-Dodecylmethylsulphonium methylsulphonylmethylid and dimethylsulphonium 1-dodecylsulphonyl methylid have been prepared. The ylids are stable crystalline solids but undergo rearrangements in solution at elevated temperatures and under the influence of ultraviolet light. Sulphonyl carbenes are not generated during these reactions.
