| titleOfInvention | Process for the preparation of 1,3-disubstituted imidazolium salts |
| abstract | Previous methods for the targeted preparation of unsymmetrically substituted 1,3-Diarylimidazoliumsalze are very rare and not applicable to all desired substitution pattern R 1 -R 4 . The problem could be solved by developing a process that allows reducing the corresponding uronium salts (I) to the desired imidazolium compounds (II). This can be done in particular by reduction with complex borohydrides in acetonitrile. With this method, a maximum variability of the radicals R 1 -R 4 is possible, so that also fused imidazolium salts such as Dipyridoimidazoliumsalze can be obtained. The products can be used as precursors of N-heterocyclic carbenes and as ionic liquids. |
