摘要

Polar addition reactions to allenes are well established and various processes involving this mechanistic pathway are known. The reaction of arenes with electrophiles is a conceptually powerful method to functionalize C-H bonds. Therefore, the feasibility of using carbon-based electrophiles, in reactions with arenes, was soon recognized as an entry for C-C bond formation. The Friedel–Crafts alkylation of arenes with alkenes is a relevant example. Nevertheless, the related alkenylation reaction involving alkynes was more slugg ishly developed and only recent advances involving metal-catalyzed transformations have made this target practicable. The reaction of arenes with the transitory species generated upon interaction of iodonium ions with alkenes or alkynes represents a powerful route for preparing cyclic compounds involving related C-C bondforming processes. Moreover, examples of Friedel–Crafts arylation reactions of allenes are rare. Recent advances involve formally related processes using precious metal catalysts and are mainly intramolecular transformations.
