Definitions

  • Y is H, Cl, CH 3 , C 2 H 5 , OCH 3 or OCF 2 H;
  • Z 1 is Cl or NHSiR 3 R 4 R 5 ;
  • R 3 is C 1 -C 4 alkyl
  • Equation 4 t-butyldimethylsilyl amine
  • Exchange may also be effected by passing an aqueous solution of a salt of a compound of Formula I (e.g., an alkali metal or quaternary amine salt) through a column packed with a cation exchange resin containing the cation to be exchanged for that of the original salt and the desired product is eluted from the column.
  • a salt of a compound of Formula I e.g., an alkali metal or quaternary amine salt
  • a cation exchange resin containing the cation to be exchanged for that of the original salt and the desired product is eluted from the column.
  • Methyl 3-Formyl-2-nitrobenzoate Methyl 3-(dibromomethyl)-2-nitrobenzoate (62.6 g), silver nitrate (109 g), 1,2-dimethoxyethane (500 mL), and water (400 mL) were heated at reflux
  • Rates of application for compounds of this invention are determined by a number of factors.
  • Compounds of this invention may be used alone or in combination with other commercial herbicides, insecticides, or fungicides.
  • the following list exemplifies some of the herbicides suitable for use in mixtures.
  • a combination of compounds from this invention with one or more of the following herbicides may be particularly useful for weed control.
  • Plant iresponse ratings are based on a scale of 0 to 10 where 0 is no effect and 10 is complete control.
  • a dash (-) response means no test result.
  • soybean (Glycine max), sugar beet (Beta vulgaris), velvetleaf (Abutilon theophrasti), wheat (Triticum aestiyum), wild buckwheat (Polygonum convolyulus), and wild oat (Ayena fatua) and purple nutsedge (Cyperus rotundus) tubers were planted and treated preemergence with test chemicals dissolved in a non-phytotoxic solvent. At the same time, these crop and weed species were also treated with
  • cocklebur Xanthium pensylvanicum
  • corn Zea mays
  • soil surface exposed and soil surface covered with perlite crabgrass (Digitaria spp.), fall panicum (Panicum dichotomiflorum), giant foxtail (Setaria faberii), green foxtail (Setaria viridis), ivyleaf morningglory (Ipomoea hederacea), jimsonweed (Datura stramonium), johnsongrass (Sorghum
