| titleOfInvention | Process for the preparation of asymmetric imidazolium salts |
| abstract | The present invention relates to a process for preparing an asymmetric imidazolium salt of formula 1A, [Chemical 1] Wherein R1 is an aromatic group, R2 is selected from secondary cycloaliphatic alkyl groups and heteroalkyl groups, and R3 and R4 are independently selected from the group consisting of hydrogen, halide and alkyl groups. A − is an anion. This process comprises a first step of forming a reaction mixture by contacting 1 equivalent of an aniline and 1 equivalent of a compound having an amino group in the presence of at least 4.5 equivalents of Bronsted acid; Forming a solution containing dicarbonyl, 1 equivalent of formaldehyde, and at least 4.5 equivalents of Bronsted acid of formula 4, and adding the reaction mixture formed in the first step; Including. Stirring at a predetermined temperature for a predetermined time, the intermediate asymmetric imidazolium salt 1A is isolated. |
