    摘要: 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-fluorobenzoate, 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.

    摘要: 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. Therefore, the compounds having Formula (III): or an agronomic salts and compositions thereof are expected to provide such control as well; wherein: Q is —NH, S, or O; W is O, or S; X is —OH, —OAc, —OR, where R is lower alkyl; Y is S, O, or —NH; Z is —Si(R)3, —C(R)3, where R is lower alkyl; R1 is a lower alkyl, allyl, or propargyl; R2 is a lower alkyl or aryl; and R3 and R4 are independently chosen from hydrogen, a lower alkyl and aryl; optionally, R2 and R3 together form a 5- or 6-membered ring.
