1,3-Dihaloazulenes were effectively transformed into 2-substituted azulenes through lithiation at the 2-position by proton abstraction. Furthermore, 1,3-dichloro-2-iodoazulene was found to undergo iodine-lithium and -magnesium exchange to generate the corresponding azulenyl-lithium and -magnesium, respectively.
1,3-二卤甘菊环通过质子提取在 2 位进行锂化,有效转化为 2-取代甘菊环。 此外,还发现1,3-二氯-2-碘甘菊环发生碘-锂和-镁交换,分别生成相应的甘菊基-锂和-镁。
