Preferred Label : photochemical reaction;
IUPAC definition : Generally used to describe a chemical reaction caused by absorption of ultraviolet,
visible or infrared radiation. There are many ground-state reactions, which have photochemical
counterparts. Among these are photochemical nitrogen extrusions, photocycloadditions,
photodecarbonylations, photodecarboxylations, photoenolizations, photo-Fries rearrangement,
photoisomerizations, photooxidations, photorearrangements, photoreductions, photosubstitutions,
etc.;
Scope note : photochemical paths offer the advantage over thermal methods of forming thermodynamically
disfavoured products, overcome large activation barriers in a short period of time,
and allow reactivity otherwise inaccessible by thermal methods.;
Origin ID : P04585;
