The aim of this thesis is to synthesize some new chiral quaternary ammonium salts and bis-quaternary ammonium salts from the popular material------Chloramphenicoland abietic acid, and then we used these chiral quaternary ammonium salts in some substitution reactions and addition reactions in order to research their catalytic action and asymmetric induction.

本文利用廉价易得的手性物质——氯霉素和去氢枞酸为初始原料，合成了几种新的季铵盐类手性相转移催化剂，扩大了手性相转移催化剂的来源，并把它们应用于取代反应和加成反应，以探讨其催化机理和不对称诱导效应。

Three kinds of ionic liquid were used to support the acetylacetone at the C3 position directly according to the method indicated above. These synthesized ionic liquid supported acetylacetone catalysts include imidazolium salts ionic liquid supported acetylacetone catalysts, pyridinium salts ionic liquid supported acetylacetone catalysts and ammonium salts ionic liquid supported acetylacetone catalysts. All these catalysts were characterized by ~1H-NMR,~(13)C-NMR, IR and elementary analysis.

采用设计过程中预期能够提高乙酰丙酮金属催化剂催化氧化活性的修饰方式，合成了三类离子液体支载的乙酰丙酮金属催化剂：咪唑型离子液体支载乙酰丙酮金属催化剂、吡啶型离子液体支载乙酰丙酮金属催化剂、胺型离子液体支载乙酰丙酮金属催化剂，并采用核磁共振氢谱、碳谱，红外光谱及元素分析来对这些新型的催化剂进行了表征。

Starting from the hydroxylamine (dimethyl amino ethanol, triethanolamine) and 1, 3-propane sultone, a series of hydroxyl and sulfonyl dual-functionalized zwitterionic salts were synthesized. Then dual-functionalized ionic liquids containing both hydroxyl and sulfonyl functional groups were produced successfully by zwitterionic salts and three kinds of strong acids (p-toluene sulfonic acid, trifluoromethanesulfonic acid, methanesulfonic acid) respectively. The structure of zwitterionic salts and dual-functional ionic liquids were confirmed by the 1H NMR and IR.
