ABSTRACT:
3,4,N-Trisubstituted-4,5-dihydro-1H-pyrazole-1-carboxamide compounds wherein the substituent in the 4-position is a 5-membered heterocyclic ring moiety containing one ring oxygen or sulfur atom and one or two ring nitrogen atoms and the substituents in the 3-posit ion and the N-position are optionally substituted phenyl moieties, such as 4,5-dihydro-3-(4-fluorophenyl)-N-(4-trifluoromethylphenyl)-4-(2-trifluorom ethyl-5-thiazolyl)-1H-pyrazole-1-carboxamide were prepared from appropriate 3,4-disubstituted-4,5-dihydro-1H-pyrazole compounds, such as 4,5-dihydro-3-(4-fluorophenyl)-4-(2-trifluoromethyl-5-thiazolyl)-1H-pyrazo le and phenyl is ocyanates and isothiocyanates, such as 4-(trifluoromethyl)phenyl isocyanate. The compounds are insecticidal.
