has been proven. In the metathesis reactions that have been carried out, the halide anion was exchanged in ionic liquid with an alkyl sulfonate based anion using alkylating agents. The results obtained using ion chromatographic analysis on the newly synthesized compounds have been discussed. Also, the utilization of a gaseous methyl halide by‐product, obtained in the metathesis reaction and otherwise
提出了一种新的合成方法以及具有烯丙基或乙基取代基以及三氟甲磺酸根,甲苯磺酸根,硫酸甲酯或甲磺酸根阴离子的氮基离子液体的全光谱(NMR,IR,MS)和离子色谱表征(IC)。在16种新型离子液体的样品上,已证明了阴离子交换方法的多功能性。在已经进行的复分解反应中,使用烷基化剂将卤化物阴离子在离子液体中与基于烷基磺酸盐的阴离子交换。讨论了使用离子色谱分析新合成的化合物获得的结果。另外,还提出了利用在易位反应中获得的气态卤代甲烷副产物的利用方法,否则该副产物难以合成。这种方法确保了整个过程的高原子经济性,
