efficient solvent-free synthesis of a new family of functionalized chiral ionic liquids based on pyridinium cation has been developed from low-cost chiral terpenoid alcohols. An exhaustive characterization was performed using state-of-the-art techniques, such as ESI–MS, ATR FT-IR and NMR (1H, 13C, 11B, 31P, 19F) spectroscopy. Thermal properties of this new class of chiral ionic liquids were studied by TGA
摘要已经从低成本的手性萜类醇开发了一种有效的无溶剂合成新的基于吡啶鎓阳离子的官能化手性离子液体家族。使用最新技术,如ESI-MS,ATR FT-IR和NMR(1 H,13 C,11 B,31 P,19 F)光谱进行了详尽的表征。通过TGA和DSC分析研究了这类新的手性离子液体的热性质。还评估了前手性苯乙酮的不对称还原反应中合成CILS的催化潜力。 图形摘要
