Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>An efficient intramolecular arene‐alkene oxidative coupling of 1, 4‐diaryl‐1, 3‐butadienes has been developed involving the use of a 2, 3‐dichloro‐5, 6‐dicyano‐<italic>para</italic>‐benzoquinone (DDQ)/acid catalyst. The reaction involves the generation of a radical cation by abstraction of an electron from the substrate with DDQ, an intramolecular Friedel–Crafts‐type reaction, and the loss of hydrogen radical.</p> <p> <boxed-text content-type="graphic" position="anchor" orientation="portrait"> <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4sx5zvf4" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /> </boxed-text> </p> </abstract>
