Abstract: Quinolinyl oxadiazole derivatives having strong herbicidal activities and excellent selectivity, especially on rice and barnyard grass, is disclosed in the present invention. Hydroxylamine chlorinate and nitrile compound are reacted in mixture solvent of water and alcohols in the presence of base to yield amidoxime. Thereafter, in the presence of base, said amidoxide is reacted with carboxylic acid chloride produced by the reaction of 3,7-dichloro-8-quinoline carboxylate and thionyl chloride to yield compound of general formula(I). In general formula(I), A and B represent hydrogen atom, sodium carbonate, etc., R represents low molecular weight alkyl, cyclo alkyl, etc.
Abstract translation: 在本发明中公开了具有强除草活性和优异选择性的喹啉基恶二唑衍生物，特别是在水稻和稗草上。 羟基胺氯化物和腈化合物在水和醇的混合溶剂中在碱的存在下反应，得到偕胺肟。 此后，在碱的存在下，所述酰胺氧化物与通过3,7-二氯-8-喹啉羧酸盐和亚硫酰氯反应生成的羧酸氯化物反应，得到通式（I）的化合物。 在通式（I）中，A和B表示氢原子，碳酸钠等，R表示低分子量烷基，环烷基等。
