[GRAPHICS]Various pyridine-, quinoline-, isoquinoline-, and pyrimidine-N-oxides were converted to their corresponding alpha-imida-zoloheteroarenes in good yield by treatment with. sulfuryl diimidazole in nonpolar solvents at elevated temperatures.

A series of seven Ru(II) complexes bearing NHC ligands have been synthesized. The electronic structures of these complexes were analysed by spectroscopic and electrochemical methods and further examined by theoretical calculations. Data show that absorption maxima are dependent on the HOMO level rather than the HOMO-LUMO gaps.
