Oxidative ring-opening of ferrocenylcyclopropylamines to N-ferrocenylmethyl β-hydroxyamides

<p>The <i>in situ</i> reduction of ferrocenyl cyclopropylimines to the corresponding amines triggers a facile oxidative ring-opening to yield the formal four-electron oxidation products: <i>N</i>-ferrocenylmethyl β-hydroxyamides. This process is believed to proceed via generation of a ferrocinium ion in the presence of air, leading to facile formation of a distonic radical cation that is ultimately trapped by oxygen.</p> <p>DOI for erratum: <a href="http://dx.doi.org/10.1039/c6ob90061e">10.1039/c6ob90061e</a></p>
