Nickel catalysis for biaryl coupling reactions has received significant attention as a less expensive and less toxic alternative to “standard” palladium catalysis. Here we describe recent developments in nickel‐catalyzed biaryl coupling methodology, along with mechanistic studies and applications. In particular we focus on nickel‐catalyzed coupling reactions in which “unreactive” bonds such as C–H, C–O, and C–C bonds are converted into biaryl moieties. Biaryl coupling through nickel catalysis has been known for a few decades. The topic has recently resurfaced in synthetic chemistry, however, thanks to its use of ideal coupling partners such as simple arenes (Ar–H) and phenol derivatives (Ar–OR). In this microreview, recent achievements in nickel‐catalyzed biaryl coupling are summarized.
