    Abstract: A novel class of chemical compounds useful as pesticides consists of N-alkoxysulfenylcarbamate esters. The preparation of these compounds, their physical properties, formulations, and use to control both household insects and crop pests are exemplified.
    Type: Grant
    Filed: September 28, 1981
    Date of Patent: July 19, 1983
    Assignee: Regents of the University of California
    Inventors: Mitsuyasu Kawata, Noriharu Umetsu, Tetsuo R. Fukuto
  • Patent number: 4350699
    Abstract: A novel class of chemical compounds useful as pesticides consists of pyridylalkoxysulfinyl derivatives of carbamate esters. The preparation of these compounds and their formulation to control insects are exemplified.
    Type: Grant
    Filed: March 30, 1981
    Date of Patent: September 21, 1982
    Assignee: The Regents of the University of California
    Inventors: Mohamed A. H. Fahmy, Tetsuo R. Fukuto, Teruomi Jojima
  • Patent number: 4344883
    Abstract: N-chlorosulfinylcarbamate esters are produced by the reaction of thionyl chloride with carbamate esters having one unsubstituted hydrogen on the carbamate nitrogen atom, preferably in the presence of a hydrogen chloride acceptor. The resulting N-chlorosulfinylcarbamate esters are useful intermediates in the preparation of pesticides having relatively low mammalian toxicity.
