  2. Hofmann elimination - Wikipedia

    en.wikipedia.org/wiki/Hofmann_elimination

    The Cope elimination is very similar to the Hofmann elimination in principle, but occurs under milder conditions. It also favors the formation of the Hofmann product, and for the same reasons. [3] An example of a Hofmann elimination (not involving a contrast between a Zaitsev product and a Hofmann product) is the synthesis of trans-cyclooctene. [4]

    These intramolecular interactions are relevant to the distribution of products in the Hofmann elimination reaction, which converts amines to alkenes. In the Hofmann elimination, treatment of a quaternary ammonium iodide salt with silver oxide produces hydroxide ions, which act as a base and eliminate the tertiary amine to give an alkene. [11]

  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. Cope reaction - Wikipedia

    en.wikipedia.org/wiki/Cope_reaction

    Consequently, the elimination product is always syn and rarely occurs with 6-membered rings. ( Rings with 5 or 7 or more members undergo the reaction just fine.) [ 6 ] [ 7 ] [ 8 ] This organic reaction is closely related to the Hofmann elimination , [2] but the base is a part of the leaving group .

  7. 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 ...

  9. Boord olefin synthesis - Wikipedia

    en.wikipedia.org/wiki/Boord_olefin_synthesis

    The Boord olefin synthesis is an organic reaction forming alkenes from ethers carrying a halogen atom 2 carbons removed from the oxygen atom (β-halo-ethers) using a metal such as magnesium or zinc. The reaction, discovered by Cecil E. Boord in 1930 [1] is a classic named reaction with high yields and broad scope. [2]
