With a strategy of the formation of benzynes by using diaryliodonium salts, a cycloadditionreaction of N-arylpyrroles with benzynes was reported. A wide range of bridge-ring amines with various substituents have been synthesized in moderate to excellent yields (35-96%). Furthermore, with a catalytic amount of TsOH·H2O, these amines can be converted into the corresponding N-phenylamine derivatives
The present invention concerns novel heteroaryl-N-aryl thiosemicarbazones and their use in pest control, as insecticides and acaπcides This invention also includes preparation of the pesticide compositions containing the compounds, and methods of controlling insects using the compounds.
