  • 3,4,N-trisubstituted-4,5-dihydro-1H-pyrazole-1-carboxamides and their use as insectioides
    Patent number: 5493024
    Abstract: 3,4,N-triaryl-4,5-dihydro-1H-pyrazole-1-carboxamide compounds having an aryl moiety in the 4-position that is an optionally substituted pyridinyl, pyrimidinyl, pyridazinyl, pyrazinyl, or quinolinyl moiety and aryl moieties in the 3-position and the N-position that are optionally substituted phenyl, pyridinyl, pyrimidinyl, pyridazinyl, pyrazinyl, or quinolinyl moieties, such as N-(4-chlorophenyl)-4,5-dihydro-3-(4-fluorophenyl)-4-(5-trifluoromethyl-2-p yridinyl)-1H-pyrazole-1-carboxamide, were prepared and found to possess insecticidal utility. 1,2-Diarylethanone compounds were converted to 1,2-diaryl-2-propen-1-one compounds by treatment with bis(dimethylamino)methane, the 1,2-diaryl-2-propen-1-one compounds were converted to 3,4-diaryl-4,5-dihydro-1H-pyrazole compounds by treatment with hydrazine, and the 3,4-diaryl-4,5-dihydro-1H-pyrazole compounds were converted to the insecticidal subject compounds by treatment with an aryl isocyanate.
    Type: Grant
    Filed: June 2, 1993
