Abstract
Catalytic isomerization of alkenes is a highly atom-economical approach to upgrade
from lower- to higher-value alkenes. Consequently, tremendous attention has been devoted
to the development of this transformation, approaches which exploit cobalt catalysis
are particularly attractive. This short review focuses on the cobalt-catalyzed alkene
isomerization, including positional isomerization, geometric isomerization, and cycloisomerization.
Three main types of reaction mechanism have been discussed to help the reader to better
understand and make meaningful comparison between the different transformations.
