Abstract

We report here a convenient synthesis of tetrabenzo [de, hi, mn, qr] naphthacenes from 1, 2- di (phenanthren-4-yl) ethynes through initial Bro̷nsted acid-catalyzed hydroarylation, followed by FeCl3-oxidative coupling reactions. This new method is applicable to tetrabenzo [de, hi, mn, qr] naphthacenes bearing various alkyl substituents.
