Abstract
Thirty-eight derivatives of N-(4-aryloxybenzyl)pyrazolecarboxamide were synthesized and their insecticidal activity was examined. Among them N-[4-(4-trifluoromethylphenoxy)benzyl]-2, 6-dimethyl-2, 4, 5, 6-tetrahydrocyclopentapyrazole-3-carboxamide (27) was found to be potent insecticide against not only hemiptera insects but also lepidoptera insect. Insecticidal activity of its enantiomers is also discussed in this paper.
