So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Back, Jisu; Park, Junbeom; Kim, Youngsuk; Kang, Haneol; Kim, Yonghwi; Park, Moon Jeong; Kim, Kimoon; Lee, Eunsung researched the compound: 2-Chloro-1,3-bis(2,6-diisopropylphenyl)-1H-imidazol-3-ium chloride( cas:1228185-09-8 ).Application of 1228185-09-8.They published the article 《Triazenyl Radicals Stabilized by N-Heterocyclic Carbenes》 about this compound( cas:1228185-09-8 ) in Journal of the American Chemical Society. Keywords: chloroimidazolium chloride preparation reaction azide; imidazolylidene triazenyl chloride preparation crystal structure one electron reduction; imidazolylidenyl triazenyl radical preparation crystal structure EPR ion battery; crystal structure imidazolylidenyl triazenyl chloride cation radical; mol structure imidazolylidenyl triazenyl chloride cation radical. We’ll tell you more about this compound (cas:1228185-09-8).
Notwithstanding the notable progress in the synthesis of N-heterocyclic carbene-stabilized radicals, aminyl radicals, supported by NHCs or otherwise, were scarcely studied due to synthetic challenges. Triazenyl radical is a particular form of aminyl radical that contains three adjacent N atoms, and offers intriguing possibilities for unique reactivity and phys. properties stemming from expected delocalization of the spin d. over the NNN moiety and its conjugated substituents. Here, the authors report the synthesis and full characterization of the 1st NHC-stabilized triazenyl radicals, obtained by 1-electron reduction of the corresponding triazenyl cations with K metal. These radicals reversibly oxidize back to the cations upon treatment with transition metal sources or electrophiles, and abstract H atom from xanthene to form a new N-H bond at the center N atom. Potential application of the redox couple between triazenyl cation and triazenyl radical was demonstrated as cathode active materials in Li ion batteries.
