4. Development of tandem and sequential reactions

When the redox isomerization reaction is followed by another consecutive reaction, this is a case of tandem reaction . A tandem reaction is defined as a process involving transformations that create two or more bonds taking place under the same reaction conditions without the addition of a reagent or a second catalyst, and in which the consecutive reactions are a direct consequence of the function formed in the previous step. Redox isomerization can be followed by tandem reactions such as C–H bond formation by hydrogen transfer, C-C bond formation, or C–F bond formation by fluorination. If a reagent and/or catalyst is added, this is no longer referred to...
