  2. Addition–elimination reaction - Wikipedia

    en.wikipedia.org/wiki/Addition–elimination...

    This gives an overall effect of substitution, and is the mechanism of the common nucleophilic acyl substitution often seen with esters, amides, and related structures. [ 1 ] Another common type of addition–elimination is the reversible reaction of amines with carbonyls to form imines in the alkylimino-de-oxo-bisubstitution reaction, and the ...

  3. Elimination reaction - Wikipedia

    en.wikipedia.org/wiki/Elimination_reaction

    Elimination reaction of cyclohexanol to cyclohexene with sulfuric acid and heat [1] An elimination reaction is a type of organic reaction in which two substituents are removed from a molecule in either a one- or two-step mechanism. [2] The one-step mechanism is known as the E2 reaction, and the two-step mechanism is known as the E1 reaction ...

  4. Ei mechanism - Wikipedia

    en.wikipedia.org/wiki/Ei_mechanism

    The selenoxide elimination has been used in converting ketones, esters, and aldehydes to their α,β-unsaturated derivatives. [1] [17] The mechanism for this reaction is analogous to the sulfoxide elimination, which is a thermal syn elimination through a 5-membered cyclic transition state. Selenoxides are preferred for this type of ...

    en.wikipedia.org/wiki/Organic_reaction

    Elimination reaction: include processes such as dehydration and are found to follow an E1, E2 or E1cB reaction mechanism: Substitution reactions: nucleophilic aliphatic substitution: with S N 1, S N 2 and S N i reaction mechanisms: nucleophilic aromatic substitution: nucleophilic acyl substitution: electrophilic substitution: electrophilic ...

  6. Reaction mechanism - Wikipedia

    en.wikipedia.org/wiki/Reaction_mechanism

    An example of a simple chain reaction is the thermal decomposition of acetaldehyde (CH 3 CHO) to methane (CH 4) and carbon monoxide (CO). The experimental reaction order is 3/2, [4] which can be explained by a Rice-Herzfeld mechanism. [5] This reaction mechanism for acetaldehyde has 4 steps with rate equations for each step :

  7. Marcus theory - Wikipedia

    en.wikipedia.org/wiki/Marcus_theory

    He solved the problem in a general way for a transfer of charge between two bodies of arbitrary shape with arbitrary surface and volume charge. For the self-exchange reaction, the redox pair (e.g. Fe(H 2 O) 6 3+ / Fe(H 2 O) 6 2+) is substituted by two macroscopic conducting spheres at a defined distance carrying specified charges. Between these ...

  8. Solvolysis - Wikipedia

    en.wikipedia.org/wiki/Solvolysis

    An example of a solvolysis reaction is the reaction of a triglyceride with a simple alcohol such as methanol or ethanol to give the methyl or ethyl esters of the fatty acid, as well as glycerol. This reaction is more commonly known as a transesterification reaction due to the exchange of the alcohol fragments.

  9. Corey–House synthesis - Wikipedia

    en.wikipedia.org/wiki/Corey–House_synthesis

    The Corey–House synthesis (also called the Corey–Posner–Whitesides–House reaction and other permutations) is an organic reaction that involves the reaction of a lithium diorganylcuprate with an organic halide or pseudohalide (′) to form a new alkane, as well as an ill-defined organocopper species and lithium (pseudo)halide as byproducts.
