A series of bromotetracenequinones 1 and bromotetracenes 2 were prepared from 4-bromophthalic anhydride. The parent tetracenequinone 1a and tetracene 2a were sparingly soluble in organic solvents. In contrast, dipropyl-substituted tetracenequinone 1b and tetracene 2b were a little more soluble. Preparation of dihexyl-substituted tetracene 2c proved to be difficult. Sonogashira coupling of 1b with trimethylsilylacetylene afforded the corresponding product.
由4-溴邻苯二甲酸酐制备了一系列溴并四苯醌1和溴并苯2。母体并四苯醌1a和并四苯2a微溶于有机溶剂。相比之下,二丙基取代的并四苯醌1b和并四苯2b的溶解度稍高一些。二己基取代的并四苯2c的制备被证明是困难的。 Sonogashira将1b与三甲基甲硅烷基乙炔偶联得到相应的产物。
