Anthracene and its 9- or 9,10-substituted (Me, Ph, Cl, Br) derivatives react with red phosphorus (Pn) in the KOH/DMSO superbase system at 85–120 °C to afford 9,10-dihydroanthracenes in good to excellent yields, thus providing simple and clean access to these extensively used dihydroaromatics.
蒽及其9或9,10取代的(Me,Ph,Cl,Br)衍生物与KOH / DMSO超碱体系中的红磷(P n)在85–120°C下反应,得到9,10-二氢蒽良好至优异的收率,因此可以轻松,清洁地获得这些广泛使用的二氢芳族化合物。
