The synthesis of 3,3'-(arylmethylene)diindolizine with a FeCl3·6H2O catalyst has been achieved with excellent efficiency at room temperature. Various indolizines were prepared by the reaction with either aromatic or aliphatic aldehydes to produce di- or triheteroarylmethanes.
以FeCl3·6H2O为催化剂,在室温下合成了3,3'-(芳基亚甲基)二
茚茚。通过与芳香醛或脂肪醛反应生成二-或三杂芳基
甲烷,制备了各种
吲哚嗪。
