The present invention provides pyrimidinone derivatives set forth by the formula:
[wherein,
R1 represents hydrogen, halogen, C1-C3alkyl or C1-C3haloalkyl;
R2, R3, R4 represents hydrogen, halogen, C1-C6alkyl, C1-C6haloalkyl, OR8, SR9, NHR10, COOR11, COR12, SO2R13, NO2 or CN, etc.;
R5 represents hydrogen, halogen or C1-C3alkyl;
R6 represents C1-C3alkyl or C1-C3haloalkyl;
R7represents nitrogen or CH;
G represents G-1, G-2, G-3, G-4 or G-5 given in the formula;
[wherein E1, E2, E3, E4, E5, E6, E7, E8, E9, E10, E11, E12, E13 or E14 each represent hydrogen, halogen or C1-C3alkyl]].
The pyrimidinone derivatives exhibit excellent herbicidal efficacy, therefore, the pyrimidinone derivatives can be used as an active ingredient for a herbicide.
本发明提供了如下式所示的嘧啶酮衍生物:
其中
R1代表氢、卤素、C1-C3烷基或C1-C3卤代烷基;
R2、R3、R4 代表氢、卤素、C1-C6 烷基、C1-C6 卤代烷基、OR8、SR9、NHR10、COOR11、COR12、SO2R13、NO2 或 CN 等;
R5 代表氢、卤素或 C1-C3 烷基;
R6 代表 C1-C3 烷基或 C1-C3 卤代烷基;
R7 代表氮或 CH;
G 代表式中给出的 G-1、G-2、G-3、G-4 或 G-5;
[其中 E1、E2、E3、E4、E5、E6、E7、E8、E9、E10、E11、E12、E13 或 E14 各自代表氢、卤素或 C1-C3 烷基]]。
嘧啶酮衍生物具有优异的除草功效,因此可用作除草剂的活性成分。
