Synthesis, Structure, and Biological Activities of [5-(Arylthio/sulfinyl/sulfonyl)-3-methyl-1-phenyl-1H-pyrazol-4-yl]-arylmethanones
摘要:
A series of novel N-phenylpyrazolyl aryl methanones derivatives containing the arylthio/sulfinyl/sulfonyl group have been synthesized via multi-step reactions from 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one and characterized by melting point, H-1 NMR, C-13 NMR, FT-IR, and HRMS. The crystal structure of (5-(4-chlorophenylsulfonyl)-3-methyl-1-phenyl-1H-pyrazol-4-yl)(2,4-dichlorophenyl)methanone containing the arylsulfonyl moiety is reported. The biological activity results showed that some of the title compounds exhibit favorable herbicidal and insecticidal activities.
