The halogenated fluorene ethers Ic–If are directly produced by the action of tetrachloro-and tetrabromo-o-benzoquinone on the corresponding halofluorene in boiling dry benzene. The preparation of the fluorene ethers by the action of tetrahalo-o-benzoquinones on 2-chloro-and 2,7-dichloro-fluorenone hydrazone is described. The ketohydrazones are readily oxidized by mercuric oxide to the corresponding 9-diazofluorenes
卤化芴醚 Ic-If 是通过四氯和四溴邻苯醌在沸腾的干燥苯中对相应的卤代芴的作用直接产生的。描述了通过四卤代-邻苯醌对 2-氯-和 2,7-二氯-芴酮腙的作用制备芴醚。酮腙很容易被氧化汞氧化成相应的 9-重氮芴,后者很容易与卤醌反应生成亚甲基醚。
