摘要
以硝基苯乙酮为原料,经α-溴代、缩合和还原3步反应制得4,4'-二氨芳基-2,2'-双噻唑(3a,3c,3e);3a,3c和3e分别与酰基芘经缩合反应合成了6个新型的希夫碱——4,4'-二[N-(芘-1-基亚烃基)胺芳基]-2,2'-双噻唑(5a^5f),其结构经1H NMR,FT-IR和元素分析表征。5a^5f的熔点均>300℃。
4,4'-Bis(am/noaryl)-2,2'-bithiazole(3a, 3c, 3e) were prepared by a three-step reaction of α-bmmination, condensation and reduction from nitro-substitute acetophenone. Six novel Schiff bases, 4,4'-his [ ( N-(pyren-l-ylmethylene) aminoaryl ) ] -2,2'-bithiazole ( 5a - 5f), were synthesized by the condensaton reaction of 3a, 3e, 3e with acyl pyrene, respectively. The structures were characterized by 1H NMR, FT-IR and elemental analysis. The melting point of 5a - 5f were above 300 ℃.
