Formula: C5H4INIn 2022 ,《Pyridine-Containing Donor-Acceptor Diarylnitroxides: Noncovalent Stabilization of the Redox States》 appeared in ChemPlusChem. The author of the article were Levitskiy, Oleg A.; Bogdanov, Alexey V.; Klimchuk, Ivan A.; Magdesieva, Tatiana V.. The article conveys some information:
A series of new pyridyl- or 2-pyridyloxide-containing donor-acceptor diarylnitroxides was obtained and characterized; high stability of the ortho-2-pyridyl-containing diarylnitroxides was determined by kinetic measurements (τ1/2=1733 h in benzene). Comparative voltammetric study of new nitroxides and their analog in which the Py replaces the Ph group revealed both through-bond and through-space stabilization of the NO redox states with the pyridyl/ 2-pyridyloxide moiety, providing reversibility of both oxidation and reduction processes. Adaptive conformational behavior of new pyridyl/pyridyloxide containing nitroxides upon one-electron oxidation and reduction was confirmed by DFT calculations Stimuli-responsive conformational changes allow switching on/off dispersion and electrostatic interactions within the mol. and increase stability of the redox states. Spectroelectrochem. measurements provided exptl. evidence for reversibility of the through-space stabilization of the oxidized state of the nitroxides with the neighboring pyridine lone pair. In the experiment, the researchers used 4-Iodopyridine(cas: 15854-87-2Formula: C5H4IN)
4-Iodopyridine(cas: 15854-87-2) is a halogenated heterocycle that is a building block for proteomics research. 4-Iodopyridine is used as a reagent in the synthesis of indazolylamides as glucocorticoid receptor agonists.Formula: C5H4IN
