Fluorine derivatives of 2,4-D (3a, 3b) show herbicidal activity against three weed species. Parent herbicides 2,4-D, MCPA, 2,4,5-T, 4-CPA, monofluorine derivatives of MCPA (3d) and 2,4,5-T (3f) show fungistatic activity against phytopatogenic fungi species Phytophtora cactorum.
芳氧基氟乙酸3a - 3h –苯氧基乙酸除草剂2,4-D,MCPA,2,4,5-T和4-CPA的氟类似物可以通过使用适当的酚和溴代二氟或苯酚高效合成,产率为29-88%。以氢化钠为碱,以二恶烷或THF为溶剂,以溴氟乙酸为溶剂。2,4-D(3a,3b)的氟衍生物显示出对三种杂草物种的除草活性。母体除草剂2,4-d,MCPA,2,4,5-T,4-CPA,MCPA(的monofluorine衍生物3D)和2,4,5-T(3F)显示出抗真菌phytopatogenic物种抑真菌活性疫恶疫霉。
