Abstract
A convenient synthesis of tert-2,7-diaminofluorenonens 3a-3e via palla dium catalyzed reaction of secondary amines with 2,7-dibromofluorene a nd subsequent oxidation is described. In the cases were non-cyclic sec ondary amines are applied, the aniline derivatives 4c-4e are formed as side products by a dehydrohalogenation reaction.
