摘　　要：以1,3-二甲基-2-咪唑啉酮,α-甲基苄胺为原料,三步合成了手性胍的氯盐,再经复分解反应,共合成了14种手性胍离子液体并对其结构性质进行了表征.该类离子液体有望用于催化不对称Henry反应、Michael加成反应等.Chiral guanidinium chloride salts were synthesized from 1,3-dimethyl-2-imidazolidinone and （S）-1-phenylethylamine. 14 ionic liquids with different anions were obtained by metathesis reactions of the chiral guanidinium chloride with MX and characterized by ^1H NMR, ^13C NMR, ESI-MS, [α]D^20 and TGA methods. These guanidinium-based ionic liquids are potential catalysts to some reactions such as asymmetric Henry reaction or Michael addition.
