anthraquinones were smoothly converted to either symmetrically or unsymmetrically substituted 9,10-bis(perfluoroalkyl)anthracene-9,10-diols by way of bistrifluoromethylation or successive trifluoromethylation-nucleophilic perfluoroalkylation, respectively, and these diols can be easily aromatized to form bis(perfluoroalkyl)anthracene derivatives in good yields by treatment with a mixture of CBr4 and PPh3.

分别通过双三氟甲基化或连续的三氟甲基化-亲核全氟烷基化的方法,将市售蒽醌平稳地转化为对称或不对称取代的9,10-双(全氟烷基)蒽-9,10-二醇,并且这些二醇很容易芳构化成双通过用CBr 4和PPh 3的混合物处理,可以得到高产率的(全氟烷基)蒽衍生物。使用含卤素的蒽衍生物的进一步交叉偶联反应实现了原始π共轭体系的成功扩展。
