N‐Heterocyclic carbenes (NHCs) have been widely employed in the construction of various metal complexes and applied in the field of catalysis. In this review, a series of palladium complexes comprising chelating bis(NHC) donors (Pd–bis(NHC) complexes) are outlined according to their application in homogeneous catalysis. Examples of metal–organic frameworks containing Pd–bis(NHC) moieties are briefly discussed, in terms of their use in heterogeneous catalysis. The catalytic applications of Pd–bis(NHC) complexes (or moieties in heterogeneous catalysts) are mainly focused on the Mizoroki–Heck, Suzuki–Miyaura, and Sonogashira coupling reactions. Another 14 types of reactions are also summarized beyond these three types of reactions. Linking ligands: N‐Heterocyclic carbenes (NHCs) have been widely employed in the construction of various metal complexes and applied in the field of catalysis (see figure). In this review, a series of palladium complexes comprising chelating bis(NHC) donors are outlined according to their application in homogeneous catalysis, with the main focus on the Mizoroki–Heck, Suzuki–Miyaura, and Sonogashira coupling reactions.
