nucleophilic substitution (SN2) is a type of reaction mechanism that is common in organic chemistry. In the SN2 reaction, a strong nucleophile forms...

simultaneously (i.e. a concerted reaction). SN2 occurs when the central carbon atom is easily accessible to the nucleophile. In SN2 reactions, there are a few conditions...

and secondary alkyl halides, the alternative SN2 reaction occurs. In inorganic chemistry, the SN1 reaction is often known as the dissociative substitution...

Pericyclic reactions, the SN2 reaction, and some rearrangements - such as the Claisen rearrangement - are concerted reactions. The rate of the SN2 reaction is...

SN2, only alkene formation by E2 elimination is observed. Thus, elimination by E2 limits the scope of the Williamson ether synthesis (an SN2 reaction)...

which is called the Klaui ligand. The Michaelis–Arbuzov reaction is initiated with the SN2 attack of the nucleophilic phosphorus species (1 - A phosphite)...

nucleophilic substitution (SN2). The two reactions are named according tho their rate law, with SN1 having a first-order rate law, and SN2 having a second-order...

Finkelstein reaction, named after the German chemist Hans Finkelstein, is a type of SN2 reaction (Substitution Nucleophilic Bimolecular reaction) that involves...

This reaction differs from a common SN2 reaction, because it happens at a trigonal carbon atom (sp2 hybridization). The mechanism of SN2 reaction does...

steps are similar to a base-catalyzed aldol reaction. The oxygen anion in this aldol-like product then SN2 attacks on the formerly-nucleophilic halide-bearing...

molecule from one enantiomeric form to the other. For example, in an SN2 reaction, Walden inversion occurs at a tetrahedral carbon atom. It can be visualized...

for SN2 reactions is quite different, as the lack of solvation on the nucleophile increases the rate of an SN2 reaction. In either case (SN1 or SN2), the...

+ RX → R−R + MX The process resembles an SN2 reaction, but the mechanism is probably complex. The reaction is intolerant of many functional groups which...

monomolecular mechanisms (respectively the SN2' and SN1'/SNi' substitutions). Allylic shifts become the dominant reaction pathway when there is substantial resistance...

substitution (SN2) reactions are concerted reactions where both the nucleophile and substrate are involved in the rate limiting step. Since this reaction is concerted...

In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical reaction occurs. A chemical mechanism...
