  2. 3,3-Dimethylpentane - Wikipedia

    en.wikipedia.org/wiki/3,3-Dimethylpentane

    A method to produce 3,3-dimethylpentane is to react tert-amyl chloride (CH 3 CH 2 (CH 3)C 2 Cl) with propionaldehyde producing 3,3-dimethylpentan-2-ol. This is then dehydrated to produce 3,3-dimethylpent-2-ene, which when hydrogenated produces some 3,3-dimethylpentane, but also 2,3-dimethylpentane. [2]

    The boiling point of 89.7 °C is 0.3 °C higher than the value of 89.4 °C predicted by Wiener's formula, based on the structure of the molecule and the boiling point of n-heptane. [2] [3] The speed of sound at 3 MHz is 1149.5 m/s at 20 °C and 889.5 m/s at 80 °C. [7] [8] [9]

  4. 2,2-Dimethylpentane - Wikipedia

    en.wikipedia.org/wiki/2,2-Dimethylpentane

    2,2-Dimethylpentane can form a clathrate hydrate with helper gas molecules. The type of clathrate formed is called "clathrate H". 2,2-Dimethylpentane was the first compound for which the structure was determined. The clathrate has 34 molecules of water per molecule, and also has xenon and hydrogen sulfide as helper molecules.

  5. Claisen rearrangement - Wikipedia

    en.wikipedia.org/wiki/Claisen_rearrangement

    The Claisen rearrangement is a powerful carbon–carbon bond-forming chemical reaction discovered by Rainer Ludwig Claisen. [1] The heating of an allyl vinyl ether will initiate a [3,3]-sigmatropic rearrangement to give a γ,δ-unsaturated carbonyl, driven by exergonically favored carbonyl CO bond formation with Δ(Δ f H) ca. −25 kcal/mol (−100 kJ/mol).

  6. 2,4-Dimethylpentane - Wikipedia

    en.wikipedia.org/wiki/2,4-Dimethylpentane

    2,4-Dimethylpentane is an alkane with the chemical formula [(H 3 C) 2 CH] 2 CH 2. This colorless hydrocarbon is produced in large quantities in oil refineries. It results from the alkylation of isobutane by propylene. [1] Often referred to as "alkylate", it is blended with other gasoline components to give a high octane fuel.

  7. Di-π-methane rearrangement - Wikipedia

    en.wikipedia.org/wiki/Di-π-methane_rearrangement

    The reaction forms (respectively) an ene- or aryl-substituted cyclopropane. Formally, it amounts to a 1,2 shift of one ene group (in the diene) or the aryl group (in the allyl-aromatic analog), followed by bond formation between the lateral carbons of the non-migrating moiety: [1] [2] Di-π-methane rearrangement
