SYNTHESIS OF N-ACETYL-N'-ARYL(HETERYL)UREAS FROM N-(1-HYDROXYIMINO-2-OXOPROPYL)PYRIDINIUM CHLORIDE

, p. 425 - 431 (2007/10/03)
N-Acetyl-N'-aryl(heteryl)ureas were synthesized by reaction of N-(1-hydroxyimino-2-oxopropyl)pyridinium chloride with amines.The use of amines on a silica support considerably increases the yield of acetylureas.
