Intramolecular Electron Transfer of Coordinated Pyrazinecarboxylato Radicals to Cobalt(III): A Pulse Radiolytic Study

Short‐lived radical intermediates of electron‐transfer reactions have only been postulated so far. An example is species 2, assumed to occur in the reduction of the complex 1 by Cr^II. The first preparation and characterization of such radicals by pulse radiolysis has now been accomplished. \documentclass{article}\usepackage{amssymb}\pagestyle{empty}\begin{document}$({\rm CH}_3)_2\mathop {\rm C}\limits^{\bullet}\raise1pt\hbox{---}{\rm OH}$\end{document} (from solvent isopropanol) served as electron‐transfer agent.
