IR and UV spectroscopy were used to assign structures to diazonium coupling products V-VII of ethyl p-toluenesulfonylacetate, benzenesulfonylacetophenone and benzenesulfonylacetanilide. The data have established that such coupling products exist largely as chelated hydrazones. An alternative synthesis of coupling products V and VII from the corresponding arylhydrazidic chlorides and sodium arenesulfinate
使用IR和UV光谱法将结构分配给对甲苯磺酰基乙酸乙酯,苯磺酰基乙酰苯和苯磺酰基乙酰苯胺的重氮偶合产物V-VII 。数据已经证实这种偶联产物主要以螯合存在。描述了由相应的芳基肼基氯化物和芳烃亚磺酸钠的偶联产物V和VII的替代合成。
