2-amino-3,5-dibromobenzaldehyde to afford 1,3-dibromo-10-chloro-8-aryl-6,7-dihydrodibenzo[b,j][1,10]phenanthroline. Also an one-pot reaction between 2 mol of 2-amino-5-chloro aryl benzophenones with 1 mol of 1,2-cyclohexanedione to get 3,10-dichloro-5,8-diaryl-6,7-dihydrodibenzo[b,j][1,10]phenanthroline has also been reported. The newly synthesized structures of the compounds were deduced by spectroscopic
摘要 已制备出一类新的二苯并[b,j][1,10]菲咯啉。在新鲜制备的伊顿试剂(五氧化二磷)存在下,通过 2-氨基-5-氯或 2'-氯/氟取代的二苯甲酮与 1,2-环己二酮的一锅反应,合成吖啶酮以非常好的收率获得– 甲磺酸),无需溶剂,通过 Friedländer 合成。然后这些中间体与 2-氨基-3,5-二溴苯甲醛反应,得到 1,3-二溴-10-氯-8-芳基-6,7-二氢二苯并[b,j][1,10]菲咯啉。2 mol 2-氨基-5-氯芳基二苯甲酮与1 mol 1,2-环己二酮一锅反应得到3,10-二氯-5,8-二芳基-6,7-二氢二苯[b, j][1,10]菲咯啉也有报道。新合成的化合物结构是通过光谱技术推导出来的。
