    The trans-cycloheptene isomerization mechanism is not simple alkene-bond rotation, but rather an alternative lower energy pathway. [2] Based on the experimentally observed second order reaction kinetics for isomerization, two trans -cycloheptene molecules in the proposed pathway first form a diradical dimer .

    en.wikipedia.org/wiki/Vinylene_carbonate

    When cyclopentadiene is used as the diene, the vicinal norbornene diol bicyclo[2.2.1]hept-5-ene-2,3-diol is formed after hydrolysis. The Swern oxidation to the 1,2-ketone bicyclo[2.2.1]hept-5-ene-2,3-dione proceeds (in the variant with trifluoroacetic anhydride instead of oxalyl chloride ) with a yield of 73%.

    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.
