摘要
提出了一种稳定溶液中硝化物还原状态的新方法。通过分子内 n → π* 相互作用,强碱性氨基氧阴离子在质子化和与溶剂形成氢键方面实现了热力学稳定。为了证明这种效果,我们合成了一种带有正酰基的新的稳定的亚硝基自由基,并采用了循环伏安法。
Competition between n → π* interactions and H-bonding: a way to stabilize aminoxyl anions and to improve electron transfer kinetics
A new approach to stabilization of the reduced state of nitroxides in solution is suggested. Thermodynamic stabilization of the strongly basic aminoxyl anions toward protonation and hydrogen bond formation with the solvent was achieved by intramolecular n → π* interactions. A new stable nitroxide radical bearing ortho-acyl group was synthesized to demonstrate this effect by means of cyclic voltammetry.
期刊介绍:
Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications.
Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
