2-(4-pyridyl)-4,6-dimethyl-1,3,5-triazine and 2-(4-pyridyl)pyrimidine have been prepared by modification of established triazine and pyrimidine syntheses. These compounds and some of their relatives have been converted to quaternary pyridinium salts. The polarographic reduction potentials of the salts in aqueous solution are pH dependent. The activity of the salts as post-emergent herbicides is reported
2-(4-吡啶基)-1,3,5-三嗪,2-(4-吡啶基)-4-甲基-1,3,5-三嗪,2-(4-吡啶基)-4,6-二甲基- 1,3,5-三嗪和2-(4-吡啶基)嘧啶是通过修饰已建立的三嗪和嘧啶合成方法制备的。这些化合物及其一些亲属已转化为季吡啶鎓盐。盐在水溶液中的极谱还原电位取决于p H。据报道这些盐作为芽后除草剂的活性。
