A series of novel Ph methoxyacrylate derivatives I [R1 = CF3, Me, Et, etc.; R2 = allyl, 3-chloroallyl, 3-methylbut-2-enyl, etc.; A = N, CH] containing a 2-alkenylthiopyrimidine substructure were designed, synthesized and evaluated in terms of acaricidal activity. (E)-Me 2-(2-((2-(3,3-dichloroallylthio)-6-(trifluoromethyl)pyrimidin-4-yloxy) methyl)phenyl)-3-methoxyacrylate I [R1 = CF3; R2 = 3,3-dichloroallyl; A = CH] exhibited significant acaricidal activity against Tetranychus cinnabarinus (T. cinnabarinus) in greenhouse tests possessing nearly twice the larvicidal and ovicidal activity compared to fluacrypyrim. Furthermore, the results of the field trials demonstrated that I [R1 = CF3; R2 = 3,3-dichloroallyl; A = CH] (II) could effectively control Panonychuscitri with long-lasting persistence and rapid action. The toxicol. data in terms of LD50 value confirmed that II had a relatively low acute toxicity to mammals, birds and honeybees. In the part of experimental materials, we found many familiar compounds, such as Ethyl 3-oxopentanoate(cas: 4949-44-4Related Products of 4949-44-4)
Ethyl 3-oxopentanoate(cas: 4949-44-4) belongs to ketone compounds. They are most widely used as solvents, especially in industries manufacturing explosives, lacquers, paints, and textiles. Ketones are also used in tanning, as preservatives, and in hydraulic fluids.Related Products of 4949-44-4
