Abstract
N-Aryl-N,N-diphenacylamine dioximes were prepared by the reaction of corresponding arylamines with alpha-bromoacetophenone oxime in ethanol-water at room temperature. These compounds reacted with aryl isocyanates in acetonitrile to give imidazooxadiazolones 9. The probable mechanism of the reaction is discussed.
