“…In 2020 a review discussing ferrocenyl migrations and molecular rearrangements based on electronic charge delocalization focused on some cationic reorganizations, however, focus was put on the groups in close proximity, and only a few examples of rearrangements occur at the ferrocenyl's periphery directly [32] . Hence, within this Section ferrocenyl‐mediated cationic rearrangements, for example, Pinacol, Beckmann, retro S E Ar (retro Friedel‐Crafts alkylations and acylations), remote Fries, and internal alkyne‐vinylidene rearrangements, as well as movements including α ‐ferrocenyl carbo cations will be discussed.…”
