Abstract

We report a one-pot Garratt–Braverman cyclization and Scholl oxidation route to polyaromatic compounds, some having a band gap below 3 eV, starting from bis-propargyl sulfones, ethers and protected amines. The method has the advantage of constructing 3 C–C bonds in one-pot in good yields.
