    Patent number: 4913728
    Abstract: Alkane- and monohaloalkane-sulfonanilides substituted in the para position by alkylthio, alkylsulfinyl and alkylsulfonyl groups and additionally substituted by halogen and optionally by trifluoromethyl and agriculturally acceptable salts thereof are useful herbicides.
    Type: Grant
    Filed: November 21, 1983
    Date of Patent: April 3, 1990

    Inventors: Sharon L. Ruffing, James R. Throckmorton
  • Process for the preparation of 4-arylthioanilines
    Patent number: 4331817
    Abstract: A process for the preparation of a 4-arylthioaniline from the corresponding 4-unsubstituted aniline which comprises reacting the latter with an alkali metal thiocyanate in the presence of halogen to provide the 4-thiocyanoaniline, reacting it with an alkali metal sulfide to convert the thiocyano moiety to an alkali metal mercaptide group followed by heating with cuprous oxide then with an aryl halide to form the desired product.
    Type: Grant
    Filed: January 16, 1981
    Date of Patent: May 25, 1982
    Assignee: Minnesota Mining and Manufacturing Co.
    Inventor: James R. Throckmorton
  • (Perhaloalkyl) thio-substituted aldehydes and ketones
    Patent number: 3937738
    Abstract: Perhaloalkanesulfenyl chlorides are reacted with aldehydes and ketones to provide novel (perhaloalkyl)thio-substituted aldehydes and ketones which are useful organic solvents and intermediates. As intermediates, these compounds are especially useful in the preparation of their carbamate derivatives which have pesticical utility.

  • Polyfluoromethylthio-substituted compounds
    Patent number: 3932508
    Abstract: The compounds 1-trifluoromethylthio-3,3-dimethyl-2, butanone-O-methylcarbamoyloxime and 1-difluoromethylthio-3,3-dimethyl-2-butanone-O-methylcarbamoyloxime are prepared from certain novel ketone and oxime intermediates. These compounds have insecticidal activity and are particularly effective against the Western and Northern corn rootworms, Diabrotica virgifera and Diabrotica longicornis respectively.
