  • Patent number: 6291513
    Abstract: The fungicidal compound 4,5-dimethyl-N-2-propenyl-2-(trimethylsilyl)-3-thiophenecarboxamide (Formula (I)) has shown superior and unexpected control of the growth of the soil-borne fungus Gaeumannomyces graminis (Gg). The present invention provides a novel compound for synthesizing the compound of Formula (I) which uses the compound 4-hydroxy-4,5-dimethyl-2-trimethylsilanyl-dihydrothiophene-3-carboxylic acid allylamide (Formula (II)) as well as novel compounds of synthesizing the allylamide. In addition, Formula (II) itself has unexpectedly been found to provide control of Gg.

  • Patent number: 6121458
    Abstract: Processes for preparing substituted 3-aryl-5-haloalkyl-pyrazoles and, specifically, for preparing C.sub.1-5 alkyl esters of 5-[1-(C.sub.1-5 alkyl)-4-halo-5-(C.sub.1-3 haloalkyl)-1H-pyrazole-3-yl]-2,4-dihalo-benzoic acids such as isopropyl 5-[4-bromo-1-methyl-5-(trifluoromethyl)-1H-pyrazole-3-yl]-2-chloro-4-fluor obenzoate, are presented. The described processes include novel approaches for forming phenyl-diketones, forming and alkylating pyrazoles, brominating heterocyclic compounds, oxidizing alkyl-substituted benzene compounds, and esterifying carboxylic acids. These processes may be combined to prepare 3-aryl-5-haloalkyl pyrazoles, or alternatively, used in subcombinations or individually to prepare intermediates or other useful compounds.
