摘要:
Novel 2-(4-(2'-fluoro-4'-cyanophenoxy)-phenoxy)alkanoic acids and agriculturally acceptable derivatives thereof are selective postemergent herbicides for the control of grassy weeds in valuable crops. The novel herbicides are surprisingly selective, i.e., exhibit little or no phytotoxic effects, to wheat, barley and especially rice at concentrations that control undesired weed grasses.
摘要:
5-Alkyl-1-(2-pyridinyl)-1H-1,2,4-triazol-3-ols are prepared in good yield by reacting an appropriate 1-acyl-1-(2-pyridinyl)-semicarbazide with a base in the presence of a non-nucleophilic solvent. The compounds so prepared are intermediates used in the preparation of insecticides. The starting semicarbazide materials are novel compounds.
摘要:
N-(3-(((2,6-Dihalophenyl)amino)sulfonyl)-1H-1,2,4-triazol-5-yl)amines, intermediates for the preparation of herbicidal substituted 1,2,4-triazolo(1,5-a)pyrimidine-2-sulfonanilides, are directly prepared from an appropriataely substituted 4-bromoaniline and a protected 5-amino-1,2,4-triazole-3-sulfonyl chloride. The improved reaction scheme involves the individual reaction steps of (a) coupling, (b) halogenation and (c) reduction.
摘要:
Aromatic diketones are prepared by a process comprising contacting at least one acylatable aromatic compound and at least one aromatic diacyl halide in the presence of catalytic amounts of ferric chloride or ferric oxide at an elevated temperature and at superatmospheric conditions.
摘要:
Monochloromethylpyridines are produced by reacting 2- or 4-methylpyridine oxides with phosphoryl chloride in the presence of an organic base. One product, 2-chloromethylpyridine, is formed by reacting 2-picoline-N-oxide with phosphoryl chloride in the presence of triethylamine.
