Özet

The N-heterocyclic carbenes (NHCs) were known as unstable and non-isolable intermediates when first discovered by Wanzlick [1] and Öfele [2] in 1968. However, after the report on the extraordinary stability, isolation, and storability of crystalline NHC IAd by Arduengo et al. in 1991 [3], numerous studies have been reported on the NHC as ligands in organic and organometallic chemistry [4]. These ligands with strong σ-donor and weak π-acceptor properties can form stable complexes with almost all transition metals [5].

Our study contains the synthesis of the new series of 2-morpholinoethyl-substituted bis-(NHC)Pd(II) complexes and their structural and spectroscopic characterization. Also, the catalytic activities of the bis-(NHC)Pd(II) complexes have been investigated that they are more efficient and stable catalysts for the direct arylation reactions of 2-n-butylfuran and 2-n-butylthiophene with aryl bromide.
