摘要:
There is provided a method for the preparation of 2-aryl-5-trifluoromethyl pyrrole compounds which are useful as insecticidal, acaricidal and nematicidal agents and as intermediates in the manufacture of said agents.
摘要:
There is provided a synthesis of 2-aryl-5-(trifluoromethyl)pyrrole compounds of formula I via the condensation of a suitable enamine with an α-haloketone.
摘要:
There is provided a single step procedure to prepare 2-aryl-5-perfluoroalkylpyrrole derivatives directly from the perfluoroacetylated Strecker reaction product. Said pyrrole derivatives are insecticidal and also useful as precursors to other insecticidal arylpyrrole compounds. Further provided are amide nitrile intermediates, useful in the preparation of insecticidal arylpyrrole compounds.
摘要:
There is provided a single step procedure for the manufacture of 1-(alkoxymethyl)pyrrole compounds by reacting the appropriate pyrrole precursor with a dihalomethane reagent in the presence of an alkali metal alkoxide. The 1-(alkoxymethyl)pyrrole compounds are useful as molluscicidal, insecticidal, acaricidal and nematocidal agents.

摘要:
There is provided a process for the preparation of 2-aryl-5-(perfluoroalkyl)pyrrole compounds of formula I from N-[1-chloro-1-(perfluoroalkyl)methyl]arylimidoyl chloride compounds. The 2-aryl-5-(perfluoroalkyl)pyrrole compounds are useful for the control of insect and acarid pests, and may also be used to prepare other pesticidal arylpyrrole compounds. In addition, the present invention provides compounds which are useful as intermediates in the preparation of arylpyrrole compounds.
