A game of dominos: Domino [4+2]/[4+2] cycloadditions between 1,8‐difurylnaphthalene and arynes provide the corresponding adducts in a highly diastereoselective manner. This new synthetic methodology enables the preparation of elusiveperylenederivatives with a remarkable reduced HOMO–LUMO gap, a crucial feature for organic semiconductors.
tandem cycloaddition reactions with high stereoselectivity. The reaction of bisfurans with dimethyl acetylenedicarboxylate (DMAD) involves tandem [4 + 2]/[4 + 2] cycloadditions in a pincer mode. The reaction of oligofurans with arynes involves stereoselective tandem [4 + 2]/[4 + 2] cycloaddition reactions in a domino mode. The corresponding aryne adducts have been transformed into extended perylene derivatives

synthetic method for the preparation of polycyclic aromatic hydrocarbons, polycyclic heteroaromatic compounds, and nanographenes. Among the many examples, anionic cyclodehydrogenation using potassium(0) has attracted synthetic chemists because of its irreplaceable reactivity and utility in obtaining rylene structures from binaphthyl derivatives. However, existing methods are difficult to use in terms of practicality
