Group 15 herbicides inhibit synthesis of certain long-chain fatty acids, thus reducing plant growth. [3] In 2001, about 7 million pounds (3,200 t) of dimethenamid were used in the United States. [4] Dimethenamid is registered for control of annual grasses, certain annual broadleaf weeds and sedges in field corn, seed corn, popcorn and soybeans.
N,N-Dimethyl-2-chloro-2-phenylethylamine (DMEA) is chemical compound that irreversibly inhibits the enzyme acetylcholinesterase. DMEA can cause intoxication in cats, resulting in respiratory failure to death, and progressive damage to the central nervous system in rats. [ 1 ]
9 – MgBr with acetone to form 2,3-dimethyl-2-pentanol, then dehydrating this alcohol to form 2,3-dimethyl-2-pentene, and hydrogenating this product. [4] The isomer is present at about 2.4% by weight in the hydrocarbon mixture obtained by the condensation of methanol at 200 °C with a zinc iodide catalyst (the main component of the mixture ...
