Allylbenzylsulfonium S-methylides 8S and dibenzylsulfonium S-methylides 18S have been generated by the fluoride ion-induced desilylation of S-benzyl-S-[(trimethylsilyl) methyl](alk-2- enyl) sulfonium salts 4S and S-benzyl-S-[(trimethylsilyl) methyl](4-substituted benzyl) sulfonium salts 7S, and the isomerized products are compared with those of the corresponding N-methylides. S-Methylides 8S selectively rearrange toward the allyl ...
