affect the efficient diazotization of arylamines. The diazoniumsalts thus obtained were coupled, using standard experimental procedures, to a range of tertiary anilines, phenols and naphthols to afford the requisite azo dyes in good yield. The diazotization and subsequent azo-coupling generated the related azo dyes at 0–5 °C in short reaction times with a simple experimental procedure.

Abstract In this study, experimental techniques such as Raman and infrared vibrational analysis and X-ray crystal diffraction were used to characterize three new azo chelate dyes derived from 1-phenyl-azo-2-naphthol (Sudan I) and its analogue 1-(xylylphenylazo)-2-naphthol (Sudan II) with metal ions. The Raman and infrared spectroscopic analysis have also provided useful information concerning the coordination
摘要 本研究采用拉曼、红外振动分析和 X 射线晶体衍射等实验技术对 1-苯基-偶氮-2-萘酚 (Sudan I) 及其类似物 1-( xylylphenylazo)-2-naphthol (Sudan II) 与金属离子。拉曼光谱和红外光谱分析还提供了有关分子复合物通过其主要波段的协调和形成的有用信息。在振动光谱中,指纹谱带,例如在 1369/1368/1359 cm -1 处的那些被分配到 [ν(CC) + δ(CH)], ν(CN)], 1351/1352/1338 cm -1 SD1Cu、SD1Co 和 SD2Ni 分别分配给 [δ(CH)] 和 816/824/813 cm -1 分配给 [ω(CH)],可用于表征此类化合物。
