以苯肼和4-取代苯乙酮(1a～1d)为原料, 经过缩合, 再与Vilsmeier-Haak试剂反应合环, 制得1-苯基-3-芳基-4-甲酰基吡唑(3a～3d), 将其与2-肼基-4/6-取代苯并噻唑(4a～4f)反应, 合成一系列新化合物1-苯基-3-芳基-吡唑-4-醛 [N-(4/6-取代苯并噻唑-2-基)]腙5～8. 所有新化合物的结构均经IR, 1H NMR, MS谱和元素分析证实. 对化合物5～8的荧光进行了测定, 结果显示这些化合物具有荧光特性, 并探讨了化合物的结构对荧光性能的影响.

By the condensation of 4-substituted acetophenones (1a～1d) with benzene hydrazine and subsequent reaction with Vilsmeier-Haak reagent, 1-phenyl-3-aryl-4-formylpyrazoles (3a～3d) were obtained. Then they reacted with 2-hydrazino-4/6-substituted benzothiazoles (4a～4f) and produced a series of novel 1-phenyl-3-arylpyrazole-4-aldehyde N-(4/6-substituted benzothiazol-2-yl) hydrazones 5～8. Their structures were es-tablished on the basis of IR, 1H NMR, MS spectra and elemental analysis. The fluorescent spectra of compounds 5～8 were detected and showed that they had fluorescence. The ef-fect of the structure of the compound on fluorescent properties was also discussed.

Key words: benzothiazole, 4-formylpyrazole, fluorescent property, benzene hydrazine
