The article provides an overview of recent advances in nickel catalysis, highlighting its unique properties and applications in various synthetic transformations. Nickel, despite being less prominent than palladium in the field of transition metal catalysis, has gained significant attention due to its ability to perform a wide range of reactions with ease. The authors discuss the historical context of nickel's use in organometallic chemistry, emphasizing its early contributions to reactions such as hydrogenation and olefin oligomerization. They then focus on recent developments in homogeneous nickel catalysis, particularly in cross-coupling reactions, where nickel has proven to be highly effective. Key advancements include the use of nickel for cross-coupling of aryl halides, phenol derivatives, benzylic electrophiles, and aziridines, as well as reductive coupling and C–H activation. The article also explores the mechanisms behind these reactions, including oxidative addition, reductive elimination, and the role of different oxidation states of nickel. Finally, the authors look forward to future developments, emphasizing the potential for nickel to complement other metals in catalysis and the need for further research to address challenges in bond formation and regioselectivity.The article provides an overview of recent advances in nickel catalysis, highlighting its unique properties and applications in various synthetic transformations.
