- BACTERICIDE COMPOSITION AND METHOD OF CONTROLLING PLANT DISEASE
-
It is to provide a fungicidal composition having stable and high fungicidal effects against cultivated crops infected with plant diseases resulting from plant diseases. A fungicidal composition containing as active ingredients (a) a benzoylpyridine derivative represented by the formula (I) or its salt: (wherein X is a halogen atom, a nitro group, a substitutable hydrocarbon group, a substitutable alkoxy group, a substitutable aryloxy group, a substitutable cycloalkoxy group, a hydroxyl group, a substitutable alkylthio group, a cyano group, a carboxyl group which may be esterified or amidated, or a substitutable amino group, n is 1, 2, 3 or 4; R1 is a substitutable alkyl group, R2' is a substitutable alkyl group, a substitutable alkoxy group, a substitutable aryloxy group, a substitutable cycloalkoxy group or a hydroxyl group, p is 1, 2 or 3, and R2" is a substitutable alkoxy group or a hydroxyl group, provided that at least two of R2' and R2" may form a condensed ring containing an oxygen atom) and (b) at least one another fungicide.

- Alkylazinylcarbonitriles as building blocks in heterocyclic synthesis: A route for the synthesis of 4-methyl-2-oxopyridines
-
The reaction of 1 with active methylene reagents afforded the enaminoamides 2 which readily cyclised to the pyridones 5. Compound 5 condensed with DMFDMA to afford the dimethylamino pyridones 8. These coupled with aryldiazonium chloride to give hydrazonoals 10. Compound 2 coupled with aromatic diazonium salts to yield the arylazopyridines 4.

- A Simple Synthesis of 2-Methoxypyridine-3-carbonitriles
-
The condensation of propanedinitrile with several enals or enones in a methanol-sodium methoxide system provides a one-step route to 2-methoxypyridine-3-carbonitriles.Together with these compounds substituted 2-aminobenzene-1,3-dicarbonitriles, were obtained as by-products.
