Preferred Label : Norrish Type I photoreaction;
IUPAC definition : α-Cleavage of an excited carbonyl compound leading to an acyl-alkyl radical pair (from
an acyclic carbonyl compound) or an acyl-alkyl diradical (from a cyclic carbonyl compound)
as a primary photoproduct.;
Scope note : decarbonylation of the primary diradical formed from cyclic carbonyl compounds and
subsequent recombination of the biradical afford very interesting cyclic compounds.; an example is:;
