The N-heterocyclic carbenes (NHCs) are one of the most important ligands for metal-catalysed reactions. NHCs have had unique properties such as stability to air and moisture, adjustability as electronically and sterically, and being strong σ-donor and weak π-acceptor [1,2]. Increasing the popularity of these ligands in organic and organometallic chemistry is due to the durability of the metal-carbene bond, as well as having thermal and oxidative stability [3,4]. The palladium-carbene complexes derived from NHC salts have been successfully synthesized as highly active catalysts in dırect arylatıon reactıon [5].
In our study, we have investigated the synthesis and the characterization of new bis-(NHC)Pd(II) complexes. Also, we investigated the catalytic activities of new bis-(NHC)Pd(II) complexes in direct arylation reactions, and they showed fairly good activity as catalysts in the direct arylation reaction.
