Herbicidal activities of phenoxypyridines was written by Fujikawa, Kanichi;Kondo, Katushide;Yokomichi, Isao;Kimura, Fumio;Haga, Takahiro;Nishiyama, Ryuzo. And the article was included in Agricultural and Biological Chemistry in 1970.Application of 4783-68-0 This article mentions the following:
Among 307 phenoxypyridines prepared, the 3-phenoxypyridines and 4-phenoxypyr idines generally showed no significant herbicidal activities, but some of the 2-phenoxypyridines were very active. 2-(4-Nitrophenoxy)-3,5-dichloropyridine was the most effective. Comparison of the activity and structure of the 2-phenoxypyridines with those of the corresponding diphenyl ethers indicated that the 2-pyridoxy group was nearly equivalent physiol. to the phenoxy group. In the experiment, the researchers used many compounds, for example, 2-Phenoxypyridine (cas: 4783-68-0Application of 4783-68-0).
2-Phenoxypyridine (cas: 4783-68-0) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Application of 4783-68-0
