| titleOfInvention | Benzyl-pyridinium and -imidazolinium ionic liquid salts for use in planar chromatography |
| abstract | The invention relates to an ionic liquid compound of formula (I)or (II) wherein each ring comprising the nitrogen atom is independently selected from the group consisting of pyridinium, imidazolium, pyrazinium, pyrrolium, pyrazolium, thiazolium, triazolium, indolium, tetrazolium, pyrimidinium, pyridazinium, piperazinium, and piperidinium; each group being optionally substituted with one, two, or three substituents selected from C 1-12 alkyl and C 1-12 alkoxy; L 1 is C 1-12 alkylene; L 2 is C 1-12 alkylene; L 3 is a single bond or C 1-12 alkylene; wherein one carbon of the C 1-12 alkylene is optionally replaced by one or more heteroatoms; Y 1 is C 6-12 aryl substituted with one, two, or three substituents each independently selected from the group consisting of halo, haloC 1-6 alkyl, and haloC 1-6 alkoxy; Y 2 is C 6-12 aryl substituted with one, two, or three substituents each independently selected from the group consisting of halo, haloC 1-6 alkyl, and haloC 1-6 alkoxy; A is selected from the group consisting of [Br], [Cl], [PF 6 ], [AsF 6 ], [SbF 6 ], [N(SO 2 CF 3 ) 2 ], [BF 4 ], [CF 3 SO 3 ], [CH 3 CO 2 ], [CF 3 SO 2 ], [NO 2 ], [NO 3 ], [ClO 4 ], [I], and [AlR 1 n 4-n R 2 n]; R 1 is halo or C 1-12 alkyl; R 2 is halo; and n is an integer selected from 0, 1, 2, 3, or 4. The invention further relates to uses of the ionic liquid compounds of the invention as well as to methods for their preparation. |
