    摘要: N-(Substituted-phenyl)-5-fluoromethyl-1,2,4­-triazolo[1,5-a]pyrimidine-2-sulfonamides of formula
    wherein:
    Y' is H, OH, Cl, CH₃, C₂H₅, OCH₃, OC₂H₅, or SCH₃;
    R¹ is H, F, Cl, Br, CH₃, CF₃, NO₂, CO₂(C₁-C₄ alkyl), or CON(C₁-C₄ alkyl)₂;
    R² is H or CH₃; and
    R³ is F, Cl, Br, NO₂, CO₂(C₁-C₄ alkyl), CON(C₁-C₄ alkyl)₂, OCH₃, or OC₂H₅; are prepared
    from 2-benzylthio-5-fluoromethyl-1,2,4-triazolo[1,5-a]-­pyrimidines and found to be herbicidal and selective to wheat and cotton, and some compounds are degradable in the soil.

    摘要: Alkyl 3-chloroanthranilates are the major product from the chlorination of alkyl esters of anthranilic acid with 1,3-dichloro-5,5-dimethylhydantoin. The 3-chloro isomer can be readily separated from the accompanying 5-chloro isomer by selective acetylation of the latter.
