Wang, Tao published the artcileSynthesis and Biological Activity of 1-(Substituted phenoxyacetoxy)-1-(pyridin-2-yl or thien-2-yl)methylphosphonates, Recommanded Product: 2-(4-(Trifluoromethyl)phenoxy)acetic acid, the publication is Journal of Heterocyclic Chemistry (2015), 52(1), 173-179, database is CAplus.
A series of novel O,O-di-Me 1-(substituted phenoxyacetoxy)-1-(pyridin-2-yl/thien-2-yl)methylphosphonates were synthesized. Structures were confirmed by IR, 1H NMR, mass spectroscopy, and elemental analyses. The results of preliminary bioassays show that some of the title compounds exhibit moderate to good herbicidal and fungicidal activities. Some possess 90-100% inhibition against most of the tested plants at the dosage of 1500 g ai/ha, whereas others possess 92-100% inhibition against Fusarium oxysporum, Phyricularia grisea, Botrytis cinereapers, Gibberella zeae, Sclerotinia sclerotiorum, and Cercospora beticola at the concentration of 50 mg/L.
Journal of Heterocyclic Chemistry published new progress about 163839-73-4. 163839-73-4 belongs to catalysis-chemistry, auxiliary class Trifluoromethyl,Fluoride,Carboxylic acid,Benzene,Ether, name is 2-(4-(Trifluoromethyl)phenoxy)acetic acid, and the molecular formula is C14H20BClO2, Recommanded Product: 2-(4-(Trifluoromethyl)phenoxy)acetic acid.
