摘要
Palladium-catalyzed cross-coupling reaction has become one of the most powerful and convenient protocol for the construction of carbon-carbon bonds in agrochemistry, pharmaceutical chemistry, materials and synthetic chemistry. In recent years, a variety of different structures of ligands and novel catalysts have been widely explored. Wherein N-heterocyclic carbene (NHC) ligands are employed as new generation catalysts in cross-coupling reactions due to low toxicity, good stability as well as appropriate coordination ability. The application of new developed Pd-NHC catalysts in cross-coupling reactions is reviewed according to the characteristics of NHC structures.
