1-[7-氟-4-炔丙基-1,4-苯并嗪-3-酮-6-基]-3-正丙基-2-硫代咪唑啉三酮的合成及其除草活性
The Synthesis and Herbicidal Activity of 1-[7-Fluoro-4-(prop-2-ynyl)-2H-benzo [b] [1,4] oxazin-3 (4H)-one-6-yl]-3-propyl-2-thioxoimidazolidinetrione (SYP-300)
【摘要】 标题化合物(SYP-300)是沈阳化工研究院的试验除草剂。由丙基异硫氰酸酯与6-氨基-7-氟-4-炔丙基-1,4-苯并嗪-3-酮经两步反应制得。其结构经核磁共振谱、红外光谱和元素分析确证。SYP-300在温室条件下100ga.i./hm2可防除多种阔叶杂草,在200ga.i./hm2对小麦和水稻安全。
【Abstract】 The title compound (SYP-300) was an experimental herbicide of Shenyang Research Institute of Chemical Industry. It was prepared by the reaction of propylisothiocyanate with 6-amino-7-fluoro-4-(prop-2-ynyl)-2H-benzo[b][1,4]oxazin-3(4H)-one. Its structure was identified by elemental analysis, IR and 1H NMR. SYP-300 showed good herbicidal activity to broad leaf weeds at 100 g a.i./hm2 and safety to rice and wheat at 200 g a.i./hm2 in glasshouse.
