Abstract

In recent years NHC ligands have an important place Keywords N-Heterocyclic carbenes · Bis-(NHC) in transition-metal chemistry due to their unique compl- Pd(II) · Single crystal X-ray diffraction · Direct arylation · exation properties, synthetic versatility and highly adjust- Butylfuran · Butylthiophene able properties [10]. Metal-NHC complexes, especially Ag(I)-NHC complexes have attracted continuous atten- tion [11]. They are used as suitable carbene transfer rea- gents for other metal–carbene complexes (as Pd, Ru, Ni, 1 Introduction Rh, and Ir) which are not always easily found [12–16]. Also, biomedical applications of Ag-NHC complexes The N-heterocyclic carbenes (NHCs) were known as such as antimicrobial, anticancer and antitumor agents unstable and non-isolable intermediates when first dis- have been researched [17–19]. covered by Wanzlick [1] and Öfele [2] in 1968. However, Pd-NHC complexes are considered to be one of the after the report on the extraordinary stability, isolation, most important classes of metal-NHC complexes. The and storability of crystalline NHC IAd by Arduengo et al. pioneering participation from the groups of Nolan in 1991 [3–5], numerous studies have been reported on [20], Herrmann [21, 22], Glorious [23] and Organ [24] the NHC as ligands in organic and organometallic chem- have been mentioned in this topic.
