摘要
合成了 10个未见文献报道的目标化合物 ,结构经IR ,1HNMR ,MS和元素分析确证 .初步除草活性测定结果表明 :目标化合物具有高效、选择除草活性 ,主要抑制双子叶植物 (如油菜 )的生长 ,而对单子叶植物 (如玉米 )
Ten 2 β (or γ )pyridinecarbonylimino 2 H 1,2,4 thiadiazolo[2,3 a ]pyrimidines were synthesized and tested for herbicidal activity. The structures of the compounds synthesized were confirmed by IR, 1H NMR and elementary analysis. The preliminary biological test shows that some of the target compounds have excellent inhibitory activities against root and stalk of dicotyledon plant (such as rape) and a good regulating activity for plant growth of monocotyledon (such as corn).
