Isomerization

In chemistry, the conversion of a molecule, so a change in the atomic sequence, or array referred to as isomerization into a different isomer. In some molecules and under certain conditions, isomerisation occurs spontaneously. Many isomers having the same or nearly the same binding energy, which takes place relatively free conversion / interconversion. Isomerization occurs within a molecule, then one speaks of a rearrangement.

Isomerization can be, for example, photochemically, thermally or catalytically effected.

Examples

  • Photochemically induced transformation of the trans - alkene in a cis- alkene.
  • Rearrangement of straight-chain to branched alkanes.
  • Conversion of one enantiomer in a racemate ( 1:1 mixture of two enantiomers).
  • Base-catalyzed conversion of allenes in alkynes.
