alkene photocycloaddition

https://doi.org/10.1351/goldbook.AT07318
Photochemical process leading to formation of a cyclobutane upon addition of an electronically excited alkene to another ground-state alkene or of an electronically excited α,β-unsaturated carbonyl compound to a ground-state alkene. The latter is called a de Mayo reaction.
Note:
A special case of photocycloaddition is a photodimerization.
