  • Patent number: 5232896
    Abstract: 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.

  • Patent number: 5034050
    Abstract: Derivatives of 4-((aryloxy)phenoxy)alkenols, their preparation and use as active herbicides for the postemergent control of grassy weeds and especially the control of said weeds in the presence of corn plants are disclosed.
    Type: Grant
    Filed: June 16, 1989
    Date of Patent: July 23, 1991

  • Patent number: 4976772
    Abstract: 4-((Aryloxy)phenoxy)alkenols, their preparation and use as active herbicides for the postemergent control of grassy weeds. The compounds also are useful as intermediates for the preparation of herbicidal derivatives, which compounds are especially useful for the control of grassy weeds in the presence of corn plants.
    Type: Grant
    Filed: November 13, 1989
    Date of Patent: December 11, 1990
    Assignee: The Dow Chemical Company
    Inventors: James A. Turner, Wendy S. Jacks, Paul S. Zorner
  • Patent number: 4900354
    Abstract: 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.
