In order to find new herbicidal leading compounds, a series of N-(4-chloro-2-fluoro-5-substituted phenyl)isoindole-1,3-dione derivatives were designed and synthesized via the strategy of linking active sub-structures which are chlorophthalim and phenoxy carboxylic ester. The target compounds were synthesized from starting material 2-chloro-4-fluoro-5-nitrophenol in four steps, and their structures were confirmed by 1H NMR, 13C NMR and HRMS. The preliminary bioassay results indicated that most compounds exhibited excellent herbicidal activities at 1,500 g/ha in both pre- and post-emergence treatments against Abutilon theophrasti and Amaranthus retroflexus. On the basis of advanced screening tests, compound 6d exhibited 100% inhibitory effect against Abutilon theophrasti and Amaranthus retroflexus at 750 g/ha, compounds 7a and 7i were much more effective against Abutilon theophrasti than com. acifluorfen with 80%-86% inhibitory activity at 22.5 g/ha. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4Related Products of 1877-75-4).
2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil. Electron-deficient reagents are also stabilized by ethers. For example, borane (BH3) is a useful reagent for making alcohols. Pure borane exists as its dimer, diborane (B2H6), a toxic gas that is inconvenient and hazardous to use. Borane forms stable complexes with ethers, however, and it is often supplied and used as its liquid complex with tetrahydrofuran (THF).Related Products of 1877-75-4
