  2. Cyclohexenone - Wikipedia

    en.wikipedia.org/wiki/Cyclohexenone

    It can be obtained from cyclohexanone by α-bromination followed by treatment with base. Hydrolysis of 3-chloro cyclohexene followed by oxidation of the cyclohexenol is yet another route. Cyclohexenone is produced industrially by catalytic oxidation of cyclohexene, for example with hydrogen peroxide and vanadium catalysts.

  3. Cyclohexanedimethanol - Wikipedia

    en.wikipedia.org/wiki/Cyclohexanedimethanol

    The reaction conducted in two steps beginning with the conversion of DMT to the diester dimethyl 1,4-cyclohexanedicarboxylate (DMCD): C 6 H 4 (CO 2 CH 3) 2 + 3 H 2C 6 H 10 (CO 2 CH 3) 2. In the second step DMCD is further hydrogenated to CHDM: C 6 H 10 (CO 2 CH 3) 2 + 4 H 2C 6 H 10 (CH 2 OH) 2 + 2 CH 3 OH. A copper chromite catalyst ...

    2 C 6 H 12 + O 22 C 6 H 11 OH. This process coforms cyclohexanone, and this mixture ("KA oil" for ketone-alcohol oil) is the main feedstock for the production of adipic acid. The oxidation involves radicals and the intermediacy of the hydroperoxide C 6 H 11 O 2 H. Alternatively, cyclohexanol can be produced by the hydrogenation of phenol ...

  5. Dimedone - Wikipedia

    en.wikipedia.org/wiki/Dimedone

    Dimedone is an organic compound with the formula (CH 3) 2 C(CH 2) 2 (CO) 2 (CH 2). Classified as a cyclic diketone, it is a derivative of 1,3-cyclohexanedione. It is a white solid that is soluble in water, as well as ethanol and methanol. It once was used as a reagent to test for the aldehyde functional group.

  6. Ring expansion and contraction - Wikipedia

    en.wikipedia.org/wiki/Ring_expansion_and_contraction

    Loss of N 2 from the diazo cations results in secondary carbocations, which tend to rearrange and then undergo hydrolysis. The reaction converts aminocyclobutane into a mixture of hydroxycyclobutane and hydroxymethylcyclopropane. These reactions produce an equilibrating mixture of two carbocations: [2] C 4 H + 7 ⇌ C 3 H 5 CH + 2

  7. Cyclohexanone - Wikipedia

    en.wikipedia.org/wiki/Cyclohexanone

    Cyclohexanone is produced by the oxidation of cyclohexane in air, typically using cobalt catalysts: [11]. C 6 H 12 + O 2 → (CH 2) 5 CO + H 2 O. This process forms cyclohexanol as a by-product, and this mixture, called "KA Oil" for ketone-alcohol oil, is the main feedstock for the production of adipic acid.

  8. 1,4-Cyclohexanedione - Wikipedia

    en.wikipedia.org/wiki/1,4-Cyclohexanedione

    1,4-Cyclohexanedione is an organic compound with the formula (CH 2) 4 (CO) 2. This white solid is one of the three isomeric cyclohexanediones . This particular diketone is used as a building block in the synthesis of more complex molecules.

  9. Gilman reagent - Wikipedia

    Lithium dimethylcopper (CH 3) 2 CuLi can be prepared by adding copper(I) iodide to methyllithium in tetrahydrofuran at −78 °C. In the reaction depicted below, [4] the Gilman reagent is a methylating reagent reacting with an alkyne in a conjugate addition, and the ester group forms a cyclic enone. Scheme 1.
