    摘要： 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.

    摘要： 2-(Phenoxy or phenylthio)-2-(pyrimidinyloxy or 1,3,5-triazinyloxy)alkanoic acid compounds, such as ethyl 2-(2-fluorophenoxy)-2-(4,6-dimethylpyrimidin-2-yloxy)-acetate, were prepared by the reaction of a phenol or thiophenol compound with a 2-chloro-2-(pyrimidinyloxy or 1,3,5-triazinyloxy)alkanoate ester compound or by the reaction of a pyrimidinol or 1,3,5-triazinol with a 2-bromo-2-(phenoxy or phenylthio)alkanoate ester. These compounds, and, especially, agriculturally acceptable salts, esters, and amides of these compounds, were found to have herbicidal utility.
