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 elusive perylene derivatives with a remarkable reduced HOMO–LUMO gap, a crucial feature for organic semiconductors.
多米诺骨牌游戏:1,8-二呋喃萘和芳烃之间的多米诺[4 + 2] / [4 + 2]环加成反应以高度非对映选择性的方式提供相应的加合物。这种新的合成方法能够制备出可消除的per衍生物,并显着减小了HOMO-LUMO间隙,这对有机半导体至关重要。
