  2. Methylenecyclohexane - Wikipedia

    en.wikipedia.org/wiki/Methylenecyclohexane

    Synthesis. It can be produced by a Wittig reaction or a reaction with a Tebbe's reagent from cyclohexanone. [1] [2] [3] It can also be synthesized as a side product ...

  3. Evelyn effect - Wikipedia

    en.wikipedia.org/wiki/Evelyn_effect

    This phenomenon contradicts the fundamental principle in organic chemistry by reactions always go by the lowest energy pathway. The favored product should remain so throughout a reaction run at constant conditions. However, the ratio of alkenes before the synthesis is complete shows that the favored product to is not the favored product.

  4. Methylcyclohexane - Wikipedia

    en.wikipedia.org/wiki/Methylcyclohexane

    Most methylcyclohexane is extracted from petroleum but it can be also produced by catalytic hydrogenation of toluene: CH 3 C 6 H 5 + 3 H 2 → CH 3 C 6 H 11. The hydrocarbon is a minor component of automobile fuel, with its share in US gasoline varying between 0.3 and 1.7% in early 1990s [10] and 0.1 to 1% in 2011. [11]

  5. Aromatization - Wikipedia

    en.wikipedia.org/wiki/Aromatization

    For cyclohexane, cyclohexene, and cyclohexadiene, dehydrogenation is the conceptually simplest pathway for aromatization. The activation barrier decreases with the degree of unsaturation. Thus, cyclohexadienes are especially prone to aromatization. Formally, dehydrogenation is a redox process. Dehydrogenative aromatization is the reverse of ...

  6. Robinson annulation - Wikipedia

    en.wikipedia.org/wiki/Robinson_annulation

    Initial synthesis gave a racemic form of the compound using an intramolecular etherification reaction of the alcohol motifs and the double bond. Yamamoto and coworkers report the use of an alternative intramolecular Robinson annulation to provide a straightforward enantioselective synthesis of tetracyclic core of platensimycin.

  7. Heck reaction - Wikipedia

    en.wikipedia.org/wiki/Heck_reaction

    This reaction was the first example of a carbon-carbon bond-forming reaction that followed a Pd(0)/Pd(II) catalytic cycle, the same catalytic cycle that is seen in other Pd(0)-catalyzed cross-coupling reactions. The Heck reaction is a way to substitute alkenes.

  8. 1-Methylcyclohexene - Wikipedia

    en.wikipedia.org/wiki/1-Methylcyclohexene

    1-Methylcyclohexene is used as a probe of the stereochemistry of reactions involving alkenes because it is prochiral and the two sp 2-carbon atoms differ. "Hydrosilylation of Cyclohexene"

  9. 3-Methylcyclohexene - Wikipedia

    en.wikipedia.org/wiki/3-Methylcyclohexene

    Synthesis. 3-Methylcyclohexene is produced from 3-methylcyclohexanone. [1] References This page was last edited on 2 November 2024, at 01:22 (UTC). Text is available ...
