As part of an ongoing program on the chemistry and biological activity of N-oxide-containingmolecules, a number of novel 1,2,5-oxadiazole N-oxide, benzo[1,2-c]1,2,5-oxadiazole N-oxide, andquinoxaline N,N'-dioxide derivatives were synthesized and evaluated for their herbicidal activity.Many of these compounds exhibited moderate to good herbicidal pre-emergence activity againstTriticum aestivum. Dose-response studies were done on the more representative compounds (12,20, and 26). The most active compound, butylcarbamoylbenzo[1,2-c]1,2,5-oxadiazole N-oxide, 26,displayed herbicidal activity at concentrations as low as 24 g/ha.Keywords: Herbicide; 1,2,5-oxadiazole N-oxide; benzo[1,2-c]1,2,5-oxadiazole N-oxide; quinoxalineN,N'-dioxide
