- Aromatic iodination in aqueous solution. A new lease of life for aqueous potassium dichloroiodate
-
A re-investigation of the use of aqueous potassium dichloroiodate (KICl2) as an iodinating agent for aromatic compounds has found the reagent to be more generally applicable than previously known. The reagent has been found to give excellent yields of iodinated heterocyclic compounds, such as isatin, imidazole and pyrazole.

- Synthesis, crystal structure and antibacterial activity of new highly functionalized ionic compounds based on the imidazole nucleus
-
Several new highly functionalized imidazolium derivatives were synthesized, via appropriate synthetic routes, using imidazole, 1-methylimidazole and 2-phenyl-1-methylimidazole as key intermediates. The antibacterial activity of the prepared compounds was evaluated against: Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella thipymurium using disk-diffusion and MIC methods. Crystal X-ray structures are reported for six compounds.

- A Pd-catalyzed double coupling reaction to 4,5-disubstituted imidazole alkynes
-
A palladium-catalyzed double coupling reaction of 4,5-diiodoimidazoles 2, which were prepared by diiodination of imidazole, and terminal alkynes provided the corresponding imidazole diynes 3.
