compounds substituted with chloro, alkylthio, and diphenylphosphino groups at the 2-position afforded dibenz[a,j]anthracene derivatives, whereas those bearing methyl, trimethylsilyl, dimethylamino, butoxy, and fluoro groups gave benzo[c]chrysene derivatives. The solubility of dibenz[a,j]anthracene in organic solvents was improved by the introduction of alkylthio groups.
已经合成了一系列在2-位带有不同取代基的1,3-二苯乙烯基苯化合物,并进行了氧化光环化过程。在2位上被氯,烷硫基和二苯基膦基取代的1,3-二苯乙烯基苯化合物提供二苯并[ a,j ]蒽衍生物,而带有甲基,三甲基甲硅烷基,二甲基氨基,丁氧基和氟基的化合物得到苯并[ c ] derivatives衍生物。通过引入烷硫基提高了苯并[ a,j ]蒽在有机溶剂中的溶解度。
