With the reference to poly(2-vinylpyridine), the ion-radical mechanism is established for the generation of stable nitrogen-containing radicals in polymers under the effect of nitrogen dioxide. The mechanism includes the reactions of nitrogen dioxide dimers occurring in the form of nitrosonium-nitrate ion pairs. The ion-radical process is induced by electron transfer from donor groups of macromols. to nitrosonium cations resulting in the formation of cation-macroradicals and nitrogen oxide. Stable radicals are generated in the course of subsequent reactions of these particles leading to the formation of macromol. nitroso compounds, which are efficient spin traps. In the experiment, the researchers used many compounds, for example, 2-Isopropylpyridine (cas: 644-98-4Application In Synthesis of 2-Isopropylpyridine).
2-Isopropylpyridine (cas: 644-98-4) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Application In Synthesis of 2-Isopropylpyridine
