Abstract

The halogenated fluorene ethers I cI f 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 which react readily with ...
