Reactions that do not introduce new functions into the substrate
Coordination catalysis - Part 1

Here, we'll focus on positional isomerization of the double bond in olefins (alkenes), which is most often accompanied by cis-trans rebalancing.

Other types of isomerization, in particular rearrangements of hydrocarbon skeletons, are relatively rare in coordination catalysis. Brief mention may be made of the rearrangement of linear 1,4-dienes into branched conjugated dienes [21] and the opening of strained polycyclic compounds, such as the transformation of quadricyclene into norbornadiene [22] .
