- Substituted pyridinesulfonamide compound or its salt, process for preparing the same, and herbicide containing the same
-
A substituted pyridinesulfonamide compound or its salt represented by the following general formula (I): STR1 wherein A is CH or N; when A is CH, R1 and R2 may be either each independently a member selected from the group consisting of unsubstituted or substituted alkyl groups, unsubstituted or substituted alkenyl groups, unsubstituted or substituted cycloalkyl groups, and unsubstituted or substituted phenyl groups; when A is N, R1 is an unsubstituted or substituted alkyl group, R2 is an unsubstituted or substituted alkyl group, or an unsubstituted or substituted alkoxy group; and X and Y are each independently a member selected from the group consisting of alkyl groups and alkoxy groups, is disclosed. This compound is useful as the effective ingredient of a herbicide showing a wide weed-control spectrum even if used in a small amount.

- SYNTHESIS, SPECTRAL PROPERTIES, AND PESTICIDAL ACTIVITY OF 4-AMINO(ALKYLAMINO, DIALKYLAMINO)-5-CHLORO-2-SUBSTITUTED-3-OXO-2H-PYRIDAZINES AND 5-AMINO(ALKYLAMINO, DIALKYLAMINO)-4-CHLORO-2-SUBSTITUTED-3-OXO-2H-PYRIDAZINES
-
4-Amino(alkylamino)-5-chloro-2-substituted-3-oxo-2H-pyridazines and 5-amino(alkylamino, dialkylamino)-4-chloro-2-substituted-3-oxo-2H-pyridazines have been prepared by nucleophilic substitution reactions of 4,5-dichloro-2-substituted-3-oxo-2H-pyridazines with amines in aprotic solvent.Structure of the compounds prepared has been proved by IR and UV spectra.Fungicidal and herbicidal activity of the compounds prepared have been tested.None of the compounds prepared exceeds the standard Vitavax in the fungicidal activity tests.Compounds VIII and XII show equal or better activity on the Hill reaction as compared with the standard pyrazone.
