Abstract:  4-Aminopicolinates with alkyl or alkenyl substituents in the 6-position (I, wherein X = H, F; Y = C1-4 alkyl, C1-4-alkoxy- or thioalkoxy-substituted alkyl, or C2-3 alkenyl; and W represents NO2, N3, NR1R2, etc.; R1 and R2 independently = H, C1-6 alkyl, etc.) and their amine and acid derivs. are potent herbicides demonstrating a broad spectrum of weed control. Thus, Me 4-amino-3-chloro-6-ethylpyridine-2-carboxylate (II) at 250 ppm controlled cocklebur (Xanthium strumarium), lamb's-quarters (Chenopodium album), and pigweed (Amaranthus retroflexus) by 95, 100, and 98%, resp. (postemergent contro.

Abstract:  Substituted dihydrotriazinones, triazinones I, wherein R1 is alkyl, haloalkyl, alkenyl, aryloxyalky, etc.; R2 is alkyl, cycloalkyl, (un)substituted Ph ring, etc.; R3 is H, alkylcarbonyl, heterocyclic ring, etc.; R4 is H, alkylcarbonyl, formyl, alkoxy, etc.; X is H, or taken with R3 to be a nitrogen -carbon bond; Z is O, S, or (un)substituted amino are prepd. for use as broad spectrum fungicides. Thus, II was prepd. and tested as a fungicide against leaf rust of wheat, cucumber anthracnose, cucumber powdery mildew, glume blotch of wheat, tomato late blight and rice blast and exhibited between ...

Abstract:  Title compds. I [R1, R2, R3 = H, halo, alkyl; A = H, alkyl; W = NH, O; D = O, NH, S; E = -(CO)p-R'; p = 0, 1; R' = rings selected from Ph, furanyl, pyridinyl, etc. (each ring is optionally substituted with alkyl, alkenyl, alkynyl, etc.); B = halo, alkyl, haloalkyl, etc.; n = 0-3; m = 0-4; with the proviso that when D is O or S and E is Ph, then E is not further substituted with halo.] were prepd. For example, reaction of 2-chloro-5-(trifluoromethyl)pyridine with tyramine followed by treatment with 4,5-dichlorothieno[2,3-d]pyrimidine afforded compd. II. Compd.

"Preparation of insecticidal, acaricidal, and nematocidal pyridine derivatives". Patent WO 2004057960.

Abstract:  The compds. QCR1R2C(:XZ)NR3R4 [Q = carbocyclyl or heterocyclyl, preferably pyridyl; X = N, CR, COR, CSOnR; CNR2, etc.; R1-5 = (cyclo)alkyl, (cyclo)alkenyl, alkoxy, aryl, etc.; n = 0, 1 or 2; Z = CN or NO2;R1CR2 = carbocyclyl or heterocyclyl] are prepd. as insecticide, acaricide or nematocides.
