Dimetallic Palladium‐NHC Complexes: Synthesis, Characterization, and Catalytic Application for Direct C−H Arylation Reaction of Heteroaromatics with Aryl Chlorides

“…HRESI and HREI were carried out on a Thermo Fisher LTQ Orbitrap XL mass spectrometer and a Thermo Q Exactive Plus mass spectrometer, respectively, at Instrument Center of National Chung Hsing University (Taiwan). 1-(Naphthalen-1-yl)-1H-imidazole [30] and 9,10-di(1H-imidazol-1-yl)anthracene, [31] 1-(4-bromophenyl)-1H-imidazole [32] were prepared according to the literature procedures.…”

1-(10-Bromoanthracen-9-yl)-1H-imidazole

“…For the preparation of the title compound, see: Lee et al (2011). For the structure of a related compound, see: Boyer et al (1993).…”

“…The title compound is a side-product in the preparation of 9,10-di(1H-imidazol-1-yl)anthracene. The latter compound is a ditopic bis(imidazole) ligand which can form intriguing coordination polymers with transition metal ions (Lee et al, et al 2011). The title compound however, features only one imidazole moiety.…”

cis- and trans-9,10-di(1H-imidazol-1-yl)-anthracene based coordination polymers of ZnII and CdII: synthesis, crystal structures and luminescence properties

“…However, due to the limited solubility of L in H 2 O-organic solvent systems, a complete dissolution of L may not take place, a situation which may explain the scarce reports of complexes with trans-L conformation. [23][24][25][26] Based on the obtained results and analyzed structures of L, it seems that not only the polarity of the solvent(s) determines the cis or trans arrangement of L, but also nature of the metal ion and the counter ion contribute to the configuration of L. The relative stiffness of L based on the central rigid anthracene moiety implies that the ligand acts as a bridging rather than a chelating ligand, which leads to the formation of polymeric structures with Zn II and Cd II rather than of molecular complexes.…”

“…Related L-based coordination polymers with Cd II , Co II , and Ni II were previously reported (Table 3). [23][24][25][26] Most of the reported CPs show trans-L, and only one example of Cd II has been reported with a mixed ligand system where L adopts cis-conformation [Cd(Hbtc)(cis-L)]·3(H 2 O). 23 This complex was obtained from water solution at 140°C under hydrothermal conditions, in which L might be quite flexible with respect to the change of conformation.…”
