Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <italic> <bold>The fluorenyl cation</bold> </italic> is a highly reactive, antiaromatically destabilized carbenium ion. In their Communication on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">page 2656 ff., </ext-link> W. Sander, E. Sanchez‐Garcia et al. report how this cation can be synthesized and spectroscopically characterized in amorphous water ice at cryogenic temperatures. In protic solvents at room temperature, the lifetime is only a few picoseconds, whereas in ice below 30 K, even after several hours, no reaction is observed.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh3xbzbdfg" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
