  3. 4-Fluoroaniline - Wikipedia

    en.wikipedia.org/wiki/4-Fluoroaniline

    A colorless liquid, it is one of three isomers of fluoroaniline. It is used as a precursor to various potential and real applications. 4-Fluoroaniline can be prepared by the hydrogenation of 4-nitrofluorobenzene. [2] It is a common building block in medicinal chemistry and related fields. [3]

  4. List of cocaine analogues - Wikipedia

    en.wikipedia.org/wiki/List_of_cocaine_analogues

    The natural isomerism of cocaine is unstable and prone to epimerization. For example, the end product of cocaine biosynthesis contains an axial C2-carbomethoxy moiety which readily undergoes epimerization to the equatorial position via saponification .

  5. Metamerism (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Metamerism_(Chemistry)

    The isomers which have been cited as examples of metamers in chemical literature consist primarily of ethers; [3] but this could by the same reasoning be extended to thioethers, secondary as well as tertiary amines, esters, secondary as well as tertiary amides, (mixed) acid anhydrides etc. Metamers in organic chemistry

    Substituents add ortho to the amine in diethyl-(meta-trifluoromethyl)aniline and ortho to the fluoride in para-fluorobenzaldehyde; When multiple substituents are comparably activating, steric hindrance dominates regioselectivity. Substituents add ortho to the methyl group in para-(tert-butyl)toluene

  8. Isomerization - Wikipedia

    en.wikipedia.org/wiki/Isomerization

    In chemistry, isomerization or isomerisation is the process in which a molecule, polyatomic ion or molecular fragment is transformed into an isomer with a different chemical structure. [1] Enolization is an example of isomerization, as is tautomerization. [2] When the isomerization occurs intramolecularly it may be called a rearrangement reaction.
