We report a one-pot GarrattâBraverman 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 CâC bonds in one-pot in good yields.
我们报告了一种从双炔丙基砜、醚和受保护的胺开始的一锅 Garratt-Braverman 环化和 Scholl 氧化路线,合成多芳族化合物,其中一些化合物的带隙低于 3 eV。该方法的优点是可以一锅法构建 3 个 C−C 债券,且收益率良好。
