IUPAC > Gold Book > alphabetical index > P > photorearrangement



Photoisomerization involving changes in the arrangement of the atoms within the molecular species. It may lead to unstable isomers that react further by, e.g., dehydrogenation, deprotonation, or other reactions.
Examples are photorearrangements of alkenes (other than cis-trans photoisomerization), of cyclohex-2-enones, of endoperoxides, of thioarenes, the di-π-methane rearrangement and others.
