Novel 1-(p-aminophenyl)-3-(p-substituted phenyl)-5-phenylformazan compounds (2a-f) and 1,1-([1,1-biphenyl]-4,4-yl)bis(3-(p-substituted phenyl)-5-phenylformazan compounds (3a-f) were synthesized by diazo coupling reactions of the prepared hydrazones (1a-f) with diazonium salts of phenylenediamine and benzidine, respectively. Novel mono-formazans were obtained with high yields under mild reaction conditions and were crystallized from methanol. Bis-formazans were purified by flash column chromatograph over silica gel. The structures of formazans and bis-formazans were confirmed by elemental analysis, HR-MS and their spectral behaviours were investigated using 1H NMR, 13C NMR, FT-IR techniques. The absorption characteristics of the compounds were examined by UV-visible spectra.
新型1-(对氨基苯基)-3-(对取代苯基)-5-苯基法莫赞化合物(2a-f)和1,1-([1,1-联苯]-4,4-基)双(3-(对取代苯基)-5-苯基法莫赞化合物)(3a-f)是通过将制备的肼酮(1a-f)与对苯二胺和苯基氨基胺的重氮盐进行重氮偶联反应合成的。在温和的反应条件下,以高产率获得了新型单法莫赞,并从甲醇中结晶。双法莫赞通过硅胶闪速柱层析进行纯化。通过元素分析、HR-MS确认了法莫赞和双法莫赞的结构,并使用1H NMR、13C NMR和FT-IR技术研究了它们的光谱行为。通过紫外-可见光谱检查了这些化合物的吸收特性。
