Abstract In the current study, a novel acidic ionic liquid catalyst based on 8-hydroxyquinoline, namely 8,8′,8″-([1,3,5-triazine-2,4,6-triyl]tris[oxy])tris(1-sulfoquinolin-1-ium)chloride (TTS), was designed and synthesized. The structure of the prepared acidic ionic liquid (AIL) was fully investigated by using Fourier transform infrared (FT-IR) spectroscopy, energy dispersive X-ray (EDX) analysis,
摘要 在当前的研究中,一种基于8-羟基喹啉的新型酸性离子液体催化剂,即8,8',8”-([[1,3,5-triazine-2,4,6-triyl] tris [oxy])tris设计并合成了(1-磺基喹啉-1-鎓)氯化物(TTS)。使用傅立叶变换红外(FT-IR)光谱,能量色散X射线(EDX)分析,热重分析/差热分析(TGA / DTA),1 HNMR对制备的酸性离子液体(AIL)的结构进行了全面研究,13 CNMR和质谱。然后,通过基于乙烯基乙烯基端基的协同氧化,成功地检测了所述AIL的催化性能对吡啶衍生物的四组分合成。 图形摘要 新型AIL(TTS)在吡啶的合成中显示出很高的效率。
