Abstract
A new synthesis of large polyaromatic hydrocarbons (PAHs) with low Clar sextets is reported (see figure). The synthetic protocol involves starting bis(biaryl)diynes, which undergo initial PtCl 2 -catalyzed aromatizations, and subsequent 2,3-dichloro-5,6-dicyano benzoquinone (DDQ) oxidation. © 2011 WILEY-VCH Verlag GmbH & Co.
