Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Planar chirality</bold>: Ring‐closing metathesis of 1, 2‐diallylmetallocenes afforded the corresponding 4, 7‐dihydroindenyl species in high yields. The metallocenes are planar chiral with two different allylic substituents, and kinetic resolution of the racemic 1, 2‐diallylmetallocene derivatives was realized by molybdenum‐catalyzed asymmetric ring‐closing metathesis with excellent enantioselectivity (see scheme).<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1v8cpxjh" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
