| 摘 要： | 设计合成了阴阳离子均具有碱性位点的新型氨基功能化碱性离子液体1-(2-氨基乙基)-3-甲基咪唑咪唑盐(2-aemim]im,3),经ESIMS和1H NMR确定了结构.2-aemim]im的碱性与氨基功能化的阳离子(2-amim]+)有关,但主要取决于咪唑阴离子(im-).TG-DSC分析显示2-aemim]im具有高的热稳定性.将2-aemim]im用于催化水相介质中芳香醛、丙二腈和酚的三组分一锅法反应制备2-氨基-4H-色烯衍生物,阴阳离子之间表现出协同促进催化作用.该催化剂具有高效和底物作用范围广的特点,应用不同的酚类及类似物,如1-萘酚、2-萘酚、间苯二酚和环己二酮,以高产率得到了相应的不同官能团取代的2-氨基-4H-苯并h]色烯(4a～4e),2-氨基-4H-苯并f]色烯(5a～se),2-氨基-4H-色烯(6a～6e)和2-氨基-4H-四氢色烯(7a～7e)四类2-氨基-4H-色烯衍生物.离子液体至少可以循环使用5次,催化活性无显著降低.

| Abstract: | 1-(2-Aminoethyl)-3-methylimidazolium imidazolide(2-aemim]im,3),a new amino-function-alized basic ionic liquid with two basic groups individually located in cation and anion,was prepared and its structure was elucidated on the basis of the ESIMS and 1H NMR spectra.The basicity of 2-aemim]im is re-lated to not only the amino-functioned cation(2-aemim]+),but also the imidazolide anion(im-).The TG-DSC analysis indicated the high thermal stability of 2-aemim]im.For the one-pot three-component re-actions of a... |
