The synthesis of substituted polyaromatic compounds that contain at least four benzene rings fused together in an angular fashion is described. Suzuki coupling of 1-bromo-3,4-dihydronaphthalene-2-carbaldehyde with a number of aromatic boronic acids affords products such as 1-(1,4-dimethoxy-3-methyl-2-naphthyl)-3,4-dihydronaphthalene-2-carbaldehyde. Exposure of these dihydronaphthalenes to potassium tert-butoxide and DMF at 80 °C yields polyaromatic compounds such as 9,14-dimethoxynaphtho[1,2-a]anthracene.
本论文描述了至少含有四个以角方式融合在一起的苯环的取代多芳香族化合物的合成。将 1-溴-3,4-二氢萘-2-甲醛与一些芳香族硼酸进行铃木偶联,可得到 1-(1,4-二甲氧基-3-甲基-2-萘基)-3,4-二氢萘-2-甲醛等产物。将这些二氢萘与叔丁醇钾和 DMF 在 80 °C 的温度下接触,会产生多芳香族化合物,如 9,14-二甲氧基萘并[1,2-a]蒽。
