Electrochemical reactions. XV. Factors which determine the rate of carbon-halogen bond fragmentation in radical anions illustrated by halogenated derivatives of quinoline, quinoxaline, and phenazine was written by Alwair, Khaled;Grimshaw, James. And the article was included in Journal of the Chemical Society, Perkin Transactions 2: Physical Organic Chemistry (1972-1999) in 1973.Electric Literature of C8H5ClN2 This article mentions the following:
Halo derivatives of quinoline, quinoxaline, and phenazine in the potential region of the 1st reduction waves were examined by polarog. and cyclic voltammetry in DMF at an Hg cathode. The stability of the C-halogen bond in a halogenated radical anion depended on bond strength and the redox potential of the substrate-radical anion couple. In the experiment, the researchers used many compounds, for example, 6-Chloroquinoxaline (cas: 5448-43-1Electric Literature of C8H5ClN2).
6-Chloroquinoxaline (cas: 5448-43-1) belongs to quinoxaline derivatives. Quinoxalines are important class of heterocyclic compounds, associated with wider pharmacological applications. The parent substance of the group, quinoxaline, results when glyoxal is condensed with 1,2-diaminobenzene. Substituted derivatives arise when α-ketonic acids, α-chlorketones, α-aldehyde alcohols and α-ketone alcohols are used in place of diketones.Electric Literature of C8H5ClN2
