Chemical constitution and activity of bipyridinium herbicides. Part XIV. Reduction potential and herbicidal activity of 4,4′-(1,3,4-thiadiazole-2,5-diyl)- and 4,4′-(1,3,4-oxadiazole-2,5-diyl)bis(1-methylpyridinium) diiodides was written by Kennedy, Debra A.;Summers, Lindsay A.. And the article was included in Journal of Heterocyclic Chemistry in 1981.Related Products of 15420-02-7 This article mentions the following:
The diquaternary salts 4,4′-(1,3,4-thiadiazole-2,5-diyl)bis(1-methylpyridinium) diiodide [23622-28-8] and 4,4′-(1,3,4-oxadiazole-2,5-diyl)bis(1-methylpyridinium) diiodide [78003-53-9] are reduced in aqueous solution in the pH range 5.4-8.0 to radical cations at a potential of -0.39 V and -0.48 V, resp. Herbicidal activity was demonstrated in postemergence tests at 8-16 kg/ha against a variety of grass flora, but herbicidal activity was 1/30 and 1/60, resp., less than that of paraquat. In the experiment, the researchers used many compounds, for example, 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7Related Products of 15420-02-7).
2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Pyridine derivatives are also useful as small-molecule 浼?helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.Related Products of 15420-02-7
