采用正交实验优化合成了碱性离子液体氢氧化1-丁基-4-二甲氨基吡啶盐, 以其为反应溶剂, 在催化剂DABCO(1,4-二氮杂二环[2.2.2]辛烷)作用下进行了芳香醛与丙烯酸甲酯的Baylis-Hillman 反应研究. 实验结果表明, 在该离子液体的存在下, 芳香醛与丙烯酸甲酯以较快的反应速度和较高产率生成目标化合物. 在此基础上, 进一步研究了水-离子液体复合体系对Baylis-Hillman 反应的影响, 取得了更快的速率及更高的产率.

The synthetic methods of alkaline ionic liquid hydroxide 1-butyl-4-dimethy1 aminopyridine were optimized by using orthogonal experimental. By using triethylene diamine (DABCO) as catalyst and alkaline ionic liquid as solvent, aromatic aldehydes with methyl acrylate’s Baylis-Hillman reaction was studied. Experimental results showed that fast reaction rate and high yield were obtained in the presence of the alkaline ionic liquid. On this basis, Baylis-Hillman reaction under the influence of water-ionic liquid composite system was further studied, and obtained better result.
