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
