| titleOfInvention | Pyrimidine salicylic acid derivative and preparation method and application thereof |
| abstract | The invention provides a pyrimidine salicylic acid derivative and a preparation method and application thereof, wherein the chemical structural formula of the derivative is shown as a formula (I), and the preparation method comprises the step of reacting acid of bispyribac-sodium with trifluoroethanol or 4-butenol in the presence of an organic solvent, triethylamine and 1-hydroxybenzotriazole to obtain the compound shown as the formula (I). The preparation method has simple operation and higher yield, and the obtained pyrimidine salicylic acid derivative has low dosage and high activity of 15g/hm 2 The compound has herbicidal activity on agricultural weeds such as dicotyledonous weeds, monocotyledonous weeds and the like, particularly has better control effect on post-emergence treatment of Chenopodium quinoa and crab grass, can be used as a candidate compound of a herbicide, provides a new choice for a new variety of the herbicide, and has potential industrial application prospect. |
