  • Fluoroalkenyl compounds and their use as pest repellents
    Patent number: 5561162
    Abstract: Fluorinated alkene compounds useful for and methods of controlling nematodes, insects, and acarids that prey on agricultural crops. Polar compounds, for example, 3,4,4-trifluoro-3-butene-1-amine or 3,4,4-trifluoro-3-butenoic acid, are particularly useful for systemic control of pests. Novel method and intermediates for the preparation of 3,4,4-trifluoro-3-butene-1-amine are also provided.
    Type: Grant
    Filed: March 8, 1995
    Date of Patent: October 1, 1996
    Assignee: Monsanto Company
    Inventor: Peter G. Ruminski
  • Solid poly-amphiphilic polymer having use in a separation process
    Patent number: 5552053
    Abstract: The present invention is directed to a solid poly-amphiphilic polymer. The polymer may be (1) a continuous film (a) which is strengthened sufficiently by cross-linking to be used alone and/or supported on a frame, (b) overlaid and/or cast on a porous hydrophobic support or (2) introduced into the pores of a microporous hydrophobic membrane. The present invention is also a process for selectively removing a dissolved species (solute or target compound) from an aqueous solution or from a gaseous stream comprising contacting said aqueous solution or gaseous stream having the dissolved species and an aqueous stripping solution or other means for removing said species with opposite sides or surfaces.

    Assignee: Monsanto Company
    Inventors: Sa V. Ho, Robert Z. Greenley, Alan S. Michaels
  • 3-pyrazolyloxypyridazines, herbicidal compositions and uses thereof
    Patent number: 5536701
    Abstract: Disclosed are certain 3-pyrazolyloxypyridazines, compositions thereof which are herbicidal and methods of using such composition for controlling undesired plants. Also disclosed are mixtures of such pyridazines and acetanilide herbicides, to which mixture a safener may be added, if desired. Intermediate compounds useful in preparing the pyrazolyloxypyridazines are also disclosed.
    Type: Grant

  • Process for making optically active .alpha.-amino ketones
    Patent number: 5364961
    Abstract: The invention includes selected novel optically active .alpha.-amino ketones which either are themselves useful or are intermediates for the preparation of known ketomethylene pseudopeptides useful as antibiotics, antibiotic enhancers, or enzyme inhibitors. Further, the present invention provides a method for dehydrogenation/asymmetrical hydrogenation to obtain essentially pure antipodes of ketomethylene pseudopeptides having two chiral centers.
