Synthesis and Bioactivity of 1-Methyl-3-aryl-6(trifluoromethyl)pyridazin-4(1H)-one Derivatives
A novel series of 3-aryl pyridazinone was proposed on the base of structure activity relationships of diverse protoporphyrinogen oxidase inhibitors. Synthetic method of 3-aryl pyridazinones was investigated and 9 compounds were synthesized for interior screening test of herbicidal activity and crop safety. Bioassay results showed that most of 3-aryl-pyridazinones exhibit excellent pre-orpost-emergence herbicidal activity. Herein, 3-(2,4-dichloro-5-(cyclopentyloxy) phenyl)1-methyl-6-(trifluoromethyl) pyridazin-4(1H)-one(Ie) with high activity was selected as a post-herbicide candidate into corn field trial. The results showed that Ie exhibited higher total effective rate against weeds at the dose of 60 g a. i./hm(2) than mesotrione at 105 g a. i./hm(2), and safety to corn after emergence as well.
