2,3,6,7,10,11-Hexamethoxytriphenylene is prepared by oxidative trimerization of 1,2-dimethoxybenzene (veratrol) with iron(III) chloride/sulfuric acid in nearly quantitative yield. The obtained crude product is almost pure. Other alkoxy-substituted triphenylenes are also synthesized by this method.
2,3,6,7,10,11-六甲氧基三苯并烯通过1,2-二
甲氧基苯(
白藜芦醇)在
氯化
铁(III)/
硫酸的作用下进行氧化三聚反应,几乎定量产出。得到的粗产品几乎是纯的。其他烷氧基取代的三苯并烯也可以通过这种方法合成。
