Tris-Imidazolium Derivatives of Isocyanuric Acid. A Lead for Tripodal Ionic Liquids and Anion Receptors

Tripodal topology of tris-imidazolium salts of isocyanuric acid derivatives is a field that has not been studied in detail. A strategy based on 1,3,5-tris(2-hydroxyethyl)-1,3,5-triazinane-2,4,6-trione was designed. This compound was converted into 3,3',3''-((2,4,6-trioxo-1,3,5-triazinane-1,3,5-triyl)tris(ethane-2,1-diyl))tris(1-methyl-1H-imidazol-3-ium) chloride in two steps through its trihalide derivative in good yields. This opens a new line of research for anionic receptors and polycationic ionic liquids.
