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.

Nucleophilic attack of acetylide anions at the two carbonyl moieties of para-quinones readily affords the corresponding diols. Subsequent reduction with stannous chloride affords a number of useful compounds, including 1,4-bis[(trimethylsilyl)ethynyl]benzene, 1,4-bis[(trimethylsilyl)ethynyl] naphthalene and 9,10-bis[(trimethylsilyl)ethynyl]anthracene. Sequential attack by different acetylide anions followed by reduction provides a useful route to differentially substituted compounds including 1-[(4-nonyloxyphenyl)ethynyl]-4- (phenylethynyl)benzene, a new luminescent liquid-crystalline material.
