| Abstract: | The title compound (SYP-298) was an experimental herbicide of Shenyang Research Institute of Chemical Industry. It was prepared by the reaction of 2-nitrobenzoic acid with 6-amino-7-fluoro-4-(prop-2-ynyl)-2H- benzob]1,4]oxazin-3(4H)-one. Its structure was identified by Mass and 1H NMR. SYP-298 showed good herbicidal activity to broad leaf weeds at 38 g a.i./hm2 and safety to rice and corn at 600 g a.i./hm2 in glasshouse. |
