Abstract

The synthesis of fluoren-9-ones having a 3, 6-bis (tertiary amino) functionality is described, in which the amino groups are introduced using either cyclic secondary amines or their N- formylated derivatives to effect nucleophilic displacement of the halogen from 3, 6- dichlorofluoren-9-one, which is derived from 4-chloroanthranilic acid.
