By the same coin, the loss of the chloride or hydroxide is fast, because the ring regains aromaticity. Recent work indicates that, sometimes, the Meisenheimer complex is not always a true intermediate but may be the transition state of a 'frontside S N 2' process, particularly if stabilization by electron-withdrawing groups is not very strong.

The terminology is typically applied to organometallic and coordination complexes, but resembles the Sn2 mechanism in organic chemistry. The opposite pathway is dissociative substitution, being analogous to the Sn1 pathway. Intermediate pathways exist between the pure associative and pure dissociative pathways, these are called interchange ...
A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground, and under water. A metal detector consists of a control box, an adjustable shaft [dubious – discuss], and a variable-shaped pickup coil. When the coil nears metal, the control box ...
This is a list of historically significant items found by metal detecting method, only excluding magnet fishing finds, since magnet fishing is usually considered a distinctively different and separate hobby from traditional metal detecting.
Competition experiment between SN2 and E2. With ethyl bromide, the reaction product is predominantly the substitution product. As steric hindrance around the electrophilic center increases, as with isobutyl bromide, substitution is disfavored and elimination is the predominant reaction. Other factors favoring elimination are the strength of the ...
Raising a different foreign policy issue, he reiterated a warning that he made on social media Saturday that Panama is charging excessive fees for use of the Panama Canal, the passageway between ...
Two women who worked for disgraced ex-NYPD honcho Jeffrey Maddrey are ensnared in the federal probe of a sex-for-overtime scandal involving another female employee, The Post has learned.
Season 2 of “Squid Game” is racking up views at a record pace. After topping Netflix’s charts last week with 68 million views in four days — Netflix’s biggest TV debut ever — the ...
