Compounds of the class comprising (quinolinyl and quinoxalinyloxy)phenoxy) alkenols, e.g., 4-(4-((6-chloro-2-quinolinyl)oxy)phenoxy)-2-penten-1-ol; and a method of preparation, comprising reacting an appropriately substituted quinoline or quinoxaline, e.g., 2,6-dichloroquinoline, with a phenolic substituted pentenol, e.g., 4-(4-hydroxyphenoxy)-2-penten-1-ol, in the presence of a base and organic solvent under an inert atmosphere with or without heat, and then recovering the product. These compounds are useful as intermediates for preparing various known herbicidal compounds and are useful in their own right as post-emergent herbicides for controlling grassy weeds in the presence of corn plants.
本类化合物包括(喹啉基和喹喔啉氧基)苯氧基烯醇,例如4-(4-((6-氯-2-喹啉基)氧基)苯氧基)-2-戊烯-1-醇;以及制备方法,包括在惰性气氛下,在有机溶剂和碱的存在下,通过将适当取代的喹啉或喹喔啉(例如2,6-二氯喹啉)与酚取代的戊烯醇(例如4-(4-羟基苯氧基)-2-戊烯-1-醇)反应,带或不带加热,然后回收产物。这些化合物可用作制备各种已知除草剂的中间体,并且在玉米植株存在的情况下,作为后发除草剂用于控制草本杂草。
