Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The cover picture shows</bold> an impression of industrial preparation of aromatized Nimodipine by sunlight and air on the arid lands. Visible light is most strongly emitted in the solar spectrum on the surface of the earth. Now Qiang Liu and co‐workers develop a metal‐free and visible‐light driven aerobic aromatization catalyzed by organic dye eosin Y bis(tetrabutyl ammonium salt) (TBA‐eosinY). With the aid of K₂CO₃, the aerobic catalytic system converts 1, 4‐dihydropyridines such as Nimodipine to their corresponding pyridine derivatives efficiently under visible light irradiation at room temperature. More details are discussed in the article by Liu <italic>et al. </italic>on page 1245–1250.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh2t6ft55b" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
