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.
A compound or an optical isomer thereof corresponding to the formula ##STR56## wherein Y and Y.sup.1 each independently represent --H or --F;
A composition which comprises an agriculturally acceptable inert adjuvant in intimate admixture with a herbicidally effective amount of a compound or an optical isomer thereof, as the active material, which corresponds to the formula ##STR57## wherein Y and Y.sup.1 each independently represent --H or --F;
A method for the postemergent kill and control of grassy weeds which comprises applying to said weeds a herbicidally effective amount of a composition comprising an agriculturally acceptable inert adjuvant in intimate admixture with, as the active material, a compound or an optical isomer thereof, as the active material, which corresponds to the formula ##STR58## wherein Y and Y.sup.1 each independently represent --H or --F;
