摘要：

The E and Z geometrical isomers of methyl [[[1-[5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrophenyl]-2-methoxyethylidene]amino]oxy]acetate (Code No. AKH-7088) were separately synthesized, and their molecular conformations were determined by two-dimensional NMR spectroscopy. Greenhouse test ing showed no significant difference between the herbicidal effects of the two isomers on broadleaf weeds such as velvetleaf, cocklebur, and morningglory in soybeans, in postemergent applications of 0.035-0.28 kg/ha. Mixtures of the two isomers in various proportions exhibited practically the same biological effects as those of each isomer alone. Soybeans exhibited excellent tolerance to the iso mers and their mixtures. © 1990, American Chemical Society. All rights reserved.
