The reaction of benzamide with thionyl chloride in the presence of pyridine gave N-sulfinylbenzamide and N,N′-dibenzoylsulfurdiimide. It has been found that N-sulfinylbenzamide reacted with styrene oxide in the presence of tetraethylammonium bromide to give 4-oxo-5-benzoyl-2,6-diphenyl-1,4,3,5-oxathiadiazepine as the main product, accompanied by lesser quantities of two N-benzoyl-phenylaminoethanols
苯甲酰胺与亚硫酰氯在吡啶存在下反应生成 N-亚磺酰基苯甲酰胺和 N,N'-二苯甲酰基硫二亚胺。发现N-亚磺酰基苯甲酰胺在四乙基溴化铵存在下与氧化苯乙烯反应,得到4-oxo-5-benzoyl-2,6-diphenyl-1,4,3,5-oxathiadiazepine作为主要产物,伴随着少量的两种 N-苯甲酰基-苯基氨基乙醇、2,5-二苯基恶唑啉、苄腈和苯甲酰胺。建议了产物的形成途径。
