Abstract
Description
Technical Field
[0001] The present invention belongs to the field of agricultural fungicides, and particularly relates to a class of acyl imine derivatives containing trifluoromethyl oxadiazole, a preparation method thereof, and an application thereof. Background Art
[0002] In agriculture, long-term use of the same pesticide variety is likely to cause diseases to develop drug resistance. Therefore, it is necessary to continuously develop new varieties with different action mechanisms. With the improvement of fluorination technology, more and more polyfluoroalkyl groups are introduced into organic compounds. Due to the pseudo mimic effect, blocking effect of fluorine atoms, as well as the unique physical and chemical properties such as the high electronegativity of fluorine atoms and the liposolubility of fluorine-containing compounds, more and more new fluorine-containing pesticide varieties have been developed, and trifluoromethyl oxadiazole derivatives are one of them.
[0003] Patent CN110054596A discloses a trifluoromethyl oxadiazole derivative, including the compound structure shown in the following formula, and its connection structure with the trifluoromethyl oxadiazole-substituted phenyl is an alkylene group, and the specific molecular structure is as follows:
[0004]
[0005] Patent CN103781764A discloses an acyl imine compound, and the structural formula is as follows:
[0006]
[0007] Patent US5250498A discloses an acyl imine compound, and the structural formula is as follows:
[0008]
