Abstract: 2,3,5,6-Tetrachloropyridine, and 2,3-dichloro-5-(trichloromethyl)pyridine are prepared by selectively chlorinating polychlorinated .beta.-picolines in the vapor phase between about 250.degree. and 450.degree. C. in the presence of specific Lewis acid halide catalysts on an inorganic support. The gamma position on the pyridine ring is usually not chlorinated in the starting material or reaction products. These compounds are useful intermediates to produce insecticides and herbicides.

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- -pyridinyl)-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.

Abstract: The present invention is directed to a ribosome inactivating protein from maize. The protein is characterized by being in a single chain proRIP inactive form that can be converted into an active form by cleavage with proteases.

Abstract: Insects, especially sucking insects, such as brown planthoppers, and phytophageous mites, such as two-spotted spider mites, are controlled by applying an oxadiazole or thiadiazole compound substituted on a carbon atom by an aliphatic nitrogen heterocyclic moiety composed of at least one five or six membered ring. The compound 3-(3-amino-1,2,4-oxadiazol-5-yl)-1-azabicyclo[2,2,2]octane is typical.
