The reverse reaction to Diels-Alder is called retro-Diels-Alder. Diels-Alder adducts decompose on heating into the diene and dienophile that formed them.

Both 1,3-butadiene (4n) and 1,3,5-hexatriene (4n + 2) cyclize with light or heat to give cyclobutene and 1,3-cyclohexadiene, respectively.
Like Diels-Alder, electrocyclic reactions are concerted and stereospecific.
