The reaction of hydroxylamines with ethyl cyanoformate leads to the formation of carbethoxyamino nitrones . UV spectroscopy provided information that suggested the nitrone structure for these compounds in solution. X-ray analysis of confirmed that it exists entirely in the nitrone form in the solid state. These nitrones are shown to be excellent starting materials for a variety of nitrogen containg
羟胺与氰基甲酸乙酯的反应导致形成乙氧基氨基硝酮。紫外光谱提供的信息表明溶液中这些化合物的硝酮结构。的X射线分析证实其完全以固态存在于硝酮形式。这些硝酮被证明是各种含氮化合物(即咪唑,苯并咪唑,苯并咪唑酮,恶二唑酮,N-芳基idine啶和喹喔啉)的极佳原料。
