Abstract
Nickel-catalyzed anti-selective alkyne functionalization reactions are reviewed with an emphasis on the
mechanisms that lead to their observed stereoselectivity. Since the isomerization
of alkenylnickel species plays a key role in a large number of these reactions, the
potential mechanisms for these processes are also described in detail.
