  2. 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 ...

  3. Porphobilinogen deaminase - Wikipedia

    en.wikipedia.org/wiki/Porphobilinogen_deaminase

    Full PBG Deaminase Mechanism. The first step is believed to involve an E1 elimination of ammonia from porphobilinogen, generating a carbocation intermediate (1). [10] This intermediate is then attacked by the dipyrrole cofactor of porphobilinogen deaminase, which after losing a proton yields a trimer covalently bound to the enzyme (2).

  4. E1cB-elimination reaction - Wikipedia

    en.wikipedia.org/wiki/E1cB-elimination_reaction

    All elimination reactions involve the removal of two substituents from a pair of atoms in a compound. Alkene, alkynes, or similar heteroatom variations (such as carbonyl and cyano) will form. The E1cB mechanism is just one of three types of elimination reaction. The other two elimination reactions are E1 and E2 reactions.

  5. Ei mechanism - Wikipedia

    en.wikipedia.org/wiki/Ei_mechanism

    In organic chemistry, the E i mechanism (Elimination Internal/Intramolecular), also known as a thermal syn elimination or a pericyclic syn elimination, is a special type of elimination reaction in which two vicinal (adjacent) substituents on an alkane framework leave simultaneously via a cyclic transition state to form an alkene in a syn elimination. [1]

  6. Zaytsev's rule - Wikipedia

    en.wikipedia.org/wiki/Zaytsev's_rule

    More generally, Zaytsev's rule predicts that in an elimination reaction the most substituted product will be the most stable, and therefore the most favored. The rule makes no generalizations about the stereochemistry of the newly formed alkene, but only the regiochemistry of the elimination reaction. While effective at predicting the favored ...

  8. Arrow pushing - Wikipedia

    en.wikipedia.org/wiki/Arrow_pushing

    Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms. [1] It was first developed by Sir Robert Robinson.In using arrow pushing, "curved arrows" or "curly arrows" are drawn on the structural formulae of reactants in a chemical equation to show the reaction mechanism.
