Abstract —An affordable DABCO-based bis-dicationic ionic salt ([(DABCO)2C3H5OH]·2Cl) was utilized for the synthesis of arylidenemalononitrile, tetrahydrobenzo[b]pyran, pyrano[2,3-d]-pyrimidinone (thione), dihydropyrano[3,2-c]chromene, and polyhydroquinoline derivatives. The significant features of the presented method are ease of preparation and handling of the catalyst, high catalytic activity, short
摘要 —一种经济实惠的基于 DABCO 的双阳离子离子盐 ([(DABCO)2C3H5OH]·2Cl) 用于合成亚芳基丙二腈、四氢苯并[b]吡喃、吡喃并[2,3-d]-嘧啶酮(硫酮),二氢吡喃并[3,2-c]色烯和聚氢喹啉衍生物。该方法的显着特点是催化剂易于制备和处理,催化活性高,反应时间短,无需柱色谱分离,后处理程序简单。此外,催化剂可以很容易地回收并在研究的反应中重复使用几个循环。
