chain reaction

https://doi.org/10.1351/goldbook.C00960
A reaction in which one or more reactive reaction @I03096@ (frequently radicals) are continuously regenerated, usually through a repetitive cycle of elementary steps (the '@P04881@ step'). For example, in the chlorination of methane by a radical @M03804@, Cl. is continuously regenerated in the chain @P04881@ steps:

In @C00958@ reactions, reactive intermediates of the same types, generated in successive steps or cycles of steps, differ in @R05271@, as in:
