合成了八种新型含α-氨基膦酸酯的嘧啶水杨酸类除草剂,用激光显微拉曼光谱对其进行了表征,对谱图进行了归属。此外还测试了这八个化合物的除草活性,对此类除草剂的实际应用提供了实验数据。 Eight novel pyrimidine salicylic acid herbicides containing a-aminophosphonate were synthesized and characterized by laser Raman spectroscopy. The spectra were assigned. In addition, the herbicidal activities of these eight compounds were also tested. The experimental data were provided for the practical application of these herbicides.
