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]

An alarming study that had Americans tossing out their black plastic kitchen utensils, toys and to-go packages earlier this month overstated the concern, the researchers admit.
Like methadone, Suboxone blocks both the effects of heroin withdrawal and an addict’s craving and, if used properly, does it without causing intoxication. Unlike methadone, it can be prescribed by a certified family physician and taken at home, meaning a recovering addict can lead a normal life, without a daily early-morning commute to a clinic.

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.
