The Sonogashira coupling, catalyzed by transition metals, has become a valuable method for forming carbon-carbon bonds. While palladium-copper was originally recognized as the most effective catalyst for this transformation, recent advances have highlighted the growing prominence of nickel-catalyzed Sonogashira reactions. Nickel has gained considerable interest due to its lower cost and more environmentally friendly profile compared to palladium. This review focuses on recent progress in nickel-catalyzed Sonogashira coupling, surveying studies published between 2021 and 2025.

Catalysis
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
Heterogeneous Catalysis
Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
The hydrogenation process takes place on the surface of...
