In an attempt to synthesise azuleno[2,1-a]azulene (1), Cu+ ion-catalysed reaction of diazomethane with 3,6,7,8-tetrahydrodibenzopentalene (4) has been investigated. Addition occurred to only one of the aromatic rings to give chiefly 1,2-benzo-4,5-cycloheptatrieno-3,6,7,8-tetrahydropentalene (13/14). Dehydrogenation of 13/14 to 11H-indeno[2.1-a]azulene has been carried out.
在试图合成azuleno [2,1-α]薁(1),铜+离子催化的重氮甲烷的反应中与3,6,7,8-tetrahydrodibenzopentalene(4)进行了研究。仅在一个芳香环上加成,主要得到1,2-苯并-4,5-环庚三烯-3,6,7,8-四氢戊烯(13/14)。已经进行了将13/14脱氢为11 H-茚并[2.1-a] az。
