The diindenocarbazole derivatives are synthesized by the reaction of 2,7-dibromo-9-hexylcarbazole with benzoyl chloride under Friedel-Crafts conditions, followed by Wolff-Kishner-Huang reduction to produce 3,6-dibenzyl-2,7-dibromo-9-hexylcarbazole, which was cyclized to form bis(indeno)-9-hexylcarbazole by palladium-catalyzed double intramolecular arylation. The diindeno-carbazole was further converted
二茚并咔唑衍生物由 2,7-dibromo-9-hexylcarbazole 与苯甲酰氯在 Friedel-Crafts 条件下反应合成,然后 Wolff-Kishner-Huang 还原生成 3,6-dibenzyl-2,7-dibromo-9 -己基咔唑,通过钯催化的双分子内芳基化环化形成双(茚并)-9-己基咔唑。二茚并咔唑进一步转化为完全烷基化的化合物。
