2. alkylation of the corresponding sulfides by a wide variety of common alkylating reagents. Unfortunately, this technique is less successful for the preparation of sterically hindered or polyaryl-substituted materials. ld The preparation of sulfonium salts of this type usually requires the use of metallic complexing reagents2 and/or the use of powerful electrophilic reagent^.^ The latter is epitomized by the sulfide arylation reaction, which requires the use ...
