In a search for new herbicides with improved biological properties and different activity spectrum, we replaced phenyl moiety by ferrocenyl in cyanoacrylates, and synthesized a series of novel cyanoacrylates containing a ferrocene moiety by the reaction of aminomethylferrocene with ethoxyethyl 2-cyano-3-methylthioacrylate (or 2-cyano-3-alkoxyacrylates) in excellent yields. The title compounds were
为了寻找具有改善的生物学特性和不同活性谱的新型除草剂,我们通过氰基丙烯酸酯中的二茂铁基取代了苯基部分,并通过氨基甲基二茂铁与乙氧基乙基2-氰基-3-甲基硫代丙烯酸酯的反应合成了一系列含有二茂铁部分的新型氰基丙烯酸酯(或2-氰基-3-烷氧基丙烯酸酯)的收率很高。通过IR,1 H-NMR光谱,EI MS和元素分析鉴定标题化合物。生物测定的结果表明,某些标题化合物表现出优异的除草活性。通常,我们发现氰基丙烯酸酯中的二茂铁基取代苯基仍保留了优异的除草活性。
