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.
Notes: - An example is:

- Decarbonylation of the primary diradical formed from cyclic @C00844@ and subsequent recombination of the @B00671@ afford very interesting cyclic compounds.
