A functionalized tetradentate imidazolium salt 9,10-bis{di[2′-(N-ethylimidazolium-1-yl)ethyl]aminomethyl}anthracene tetrakis(hexafluorophosphate) (1) has been synthesized and characterized. The catalytic activity of the NHC-PdCl2 species formed by compound 1 and PdCl2 was tested in Suzuki-Miyaura, Heck-Mizoroki and Sonogashira reactions. The results showed that this catalytic system was effective for above three types of C-C coupling reactions.

Palladium compounds such as Pd(PPh//3)//4 and Pd(OAc)//2 catalyze polycondensation between dihalo aromatic compounds, X-Ar-X (Ar equals p-phenylene, 2,5-thiophenediyl, 9,10-anthracenediyl, 2,6-pyridinediyl, p-benzene-dicarbonyl, p-xylene- alpha , alpha prime -diyl), and acetylenic compounds (p-C//6H//4(C EQUVLNT CH)//2 or p-C//6H//4(C EQUVLNT CMgBr)//2). The polymers obtained have high thermal stabilities and most of them show fluorescence. One of the polymers is converted into semiconductors by doping with electron acceptors.

The 9,10-bis(3-aryl-2-naphthyl)anthracenes 3 were prepared by the benzannulation reaction of 2-(phenylethynyl)benzaldehyde (1) and the corresponding 9,10-bis(arylethynyl)anthracenes 2 in the presence of Cu or Re catalyst and trichloroacetic acid. The photophysical properties of 3 in solutions were investigated.
Luminescent assays for ketones and aldehydes employing catalytic signal amplification

, p. 729 - 735 (2007)
Herein we report the first use of transition metal catalytic signal enhancement for the analysis of small organic analytes. Two assays using Sonogashira and Suzuki cross-couplings have been used in the detection of ketones and aldehydes produce highly luminescent markers. The latter analysis utilizing the Suzuki coupling demonstrates the first use of peroxyoxalate initiated chemiluminescence in a sensing application. Chemiluminescent measurement revealed much higher sensitivity than fluorescence. The Royal Society of Chemistry and the Centre National de la Recherche Scientifique.

Two bis-imidazolium salts LH2·Cl2 and LH2·(PF6)2 with acylated piperazine linker and two N-heterocyclic carbene (NHC) silver(I) and palladium(II) complexes [L2Ag2](PF6)2 (1) and [L2Pd2Cl4] (2) were prepared. The crystal structures of LH2·Cl2 and 1 were confirmed by X-ray analysis. In 1, one 26-membered macrometallocycle was generated through two silver(I) ions and two bidentate ligands L. The catalytic activity of 2 was investigated in Sonogashira, Heck-Mizoroki and Suzuki-Miyaura reactions. The results displayed that these C—C coupling reactions can be smoothly carried out under the catalysis of 2.
