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