  2. Fluorobenzene - Wikipedia

    en.wikipedia.org/wiki/Fluorobenzene

    PhF behaves rather differently from other halobenzene derivatives owing to the pi-donor properties of fluoride. For example, the para position is more activated than benzene toward electrophiles. For this reason, it can be converted to 1-bromo-4-fluorobenzene with relatively high efficiency. [3]

    [1] [2] These conditions are successful for highly deactivated arenes, including nitroaromatics. In a series of studies, the powerful reagent obtained by using a mixture of iodine and potassium iodate dissolved in concentrated sulfuric acid was used. Here the iodinating agent is the triiodine cation I 3 + and the base is HSO 4 −.

    For example, 2,4-dinitrochlorobenzene reacts in basic solution to give a phenol. Unlike in most other substitution reactions, fluoride is the best leaving group, and iodide the worst. [ 16 ] A 2018 paper indicates that this situation may actually be rather common, occurring in systems that were previously assumed to proceed via S N Ar mechanisms.
