1,5-Diaminoanthracene and 5,6-diaminoacenaphthene readily undergo double Skraup cyclisation to benzo[1,2-h : 4,5-h′]diquinoline and dipyrido[2,3-e : 2,3-h]acenaphthene. Under the same conditions however, 3,6-diaminoacenaphthene gave only a monocyclisation product, 3-aminoindeno[1,7-gh]quinoline, and 3,8-diaminoacenaphthene remained pratically unchanged; this suggests bond fixation in the aromatic framework
1,5-二氨基蒽和5,6-二氨基ac并容易经历双Skraup环化反应生成苯并[1,2- h:4,5- h ']二喹啉和二吡啶并[2,3- e:2,3- h ] ac 。然而,在相同条件下,3,6-二氨基ac只有一个单环化产物,3-氨基茚并[1,7- gh ]喹啉,而3,8-二氨基ac却基本上没有变化。这表明这两种二胺在芳族骨架中的键固定。Nmr光谱用于确定of中间体的结构。
