摘要
利用烃基异硫氰酸酯分别与邻肼基苯甲酸、５－溴邻肼基苯甲酸、３，５－二溴邻肼基苯甲酸的加成反应，合成了１１种未见文献报道的芳胺基硫脲类化合物。通过对这些化合物的红外光谱的分析和比较，归属了它们的主要红外吸收峰，考察了主要吸收峰随取代基的变化规律。
In this paper,eleven new thiourea compounds were prepared and studied by IR spectroscopy.The fundamental vibrations have been assigned.The band near 1540cm -1 was identified as thiourea Ⅰ band,which mainly originated from the N—H deformation vibration coupling with a little C—N stretching vibration.Thiourea Ⅱ band near 1280cm -1 mainly originated from C—N stretching vibration.C=S stretching vibration frequency was at near 110cm -1 and it was identified as thiourea Ⅲ band.
