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.
A 1,2-diaryl-2-propen-1-one compound of the formula ##STR10## wherein Y represents a 5-substituted-2-pyridinyl, 6-substituted-3-pyridinyl, (6 or 7)-substituted-2-quinolinyl, (6 or 7)-substituted-3-quinolinyl, 5-substituted-2-pyrimidinyl, 2-substituted-5-pyrimidinyl, 5-substituted-2-pyrazinyl, or 6-substituted-3-pyridazinyl moiety, each moiety being substituted in the designated position by one of F, Cl, Br, CN, COQ, CF.sub.3, OR', SR', and OAr;
A 1,2-diarylethanone compound of the formula ##STR11## wherein Y represents a 5-substituted-2-pyridinyl, 6-substituted-3-pyridinyl, (6 or 7)-substituted-2-quinolinyl, (6 or 7)-substituted-3-quinolinyl, 5-substituted-2-pyrimidinyl, 2-substituted-5-pyrimidinyl, 5-substituted-2-pyrazinyl, or 6-substituted-3-pyridazinyl moiety, each moiety being substituted in the designeted position by one of F, Cl, Br, CN, COQ, CF.sub.3, OR', SR', and OAr;
