Nickel catalyzed hydroamination reactions: An overview

Hydroamination is a valuable method for the synthesis of synthetically relevant nitrogen-containing compounds including amines, imines or enamines. Owing to the low cost, non-toxicity, and unique reactivity, Nickel complexes are explored as catalysts in hydroamination in the last decades. This review encompasses various nickel complexes in both heterogeneous and homogeneous systems. The homogeneous catalytic systems comprise Ni-nitrogen, Ni–phosphorus and Ni–NHC based catalysts. This is the first review that solely discusses nickel catalyzed hydroamination of C–C multiple bonded substrates and covers literature up to 2021. [Display omitted]
